Online Arctan 1 Tutors - Arctan 1 Online Tutoring In trigonometry, tan is a trigonometric function where stands for the angle. The tangent of an angle , tan is the opposite side divided by the adjacent side in a triangle. Arctan is the inverse of tangent and by taking the inverse tangent, we find the value of . Arctan(1) is the inverse tangent of 1 and the angle value of it is 45. Example 1: Find the angle, x if in a triangle the opposite side to angle x is 20m and the adjacent side is also 20m. Given in a triangle, the opposite side = 20m The adjacent side = 20m The tangent of an angle, tanx = opposite side/adjacent side tanx = 20/20 hence tanx = 1 Now in order to find the value of the angle, x we have to get the tan to the right side, and it becomes arctan or inverse tangent. Now we get: x = arctan(1) = 45 Hence in the triangle, the angle, x = 45 Example 2: Find the angle, if in a triangle the opposite side to angle is 60cm and the adjacent side is also 60cm. Given in a triangle, the opposite side = 60cm The adjacent side = 60cm The tangent of an angle, tan = opposite side/adjacent side tan = 60/60 hence tan = 1 Now in order to find the value of the angle, we can take the tan to the other side, and it becomes arctan or inverse tangent. Now we get: = arctan(1) = 45 Hence in the triangle, the angle, = 45

Basic Geometry Equations and Examples

Basic Geometry Equations and Examples Mastering Basic Equations of Geometry ChaptersThe Basic ShapesCalculating TrianglesCalculating QuadrilateralsCalculating PolygonsCalculating CirclesSome people might say that geometry is in no way a ‘sexy’ subject; really, as a general rule, calculating angles, volumes and areas is seldom considered enticing or fun.Could the opposite be true?Over the last 10 years, we’ve seen mathematics creeping into films and television shows; The Big Bang Theory is a prime example of such. Granted, equations are not central to the plot and, quite frankly, only the first few shows were math-heavy. After that, algebraic work popped up only occasionally.Still, it is nice to see complex calculations playing out in a popular arena, and it’s even better that both male and female characters take part in tweaking the equations; a  mere 20 years ago, cinematic mathematicians could only be male!Now it’s your turn to master basic geometry equations and you want the most efficient way of doing so. Or maybe you’re a fan of Descartes an d wish to take Cartesian geometry to the next level but you need a solid foundation, first.Your Superprof wants to help you get a good grasp of fundamental geometrical formulas; grab your squares and compasses… we’re off!

Image by monicore from PixabayYou might be tempted to think ‘circle’, ‘triangle’ or ‘square’ and you’d be absolutely correct.Each of those geometric shapes fall into one of these four general categories:Triangles have three sides; the sides may be of equal length (equilateral triangle) or all different length (scalene triangle).A quadrilateral is any four-sided polygon. Those would be rectangles, squares, rhombuses, diamonds…the parallelogram, a shape that has 2 pairs of equal sides, is also a quadrilateralPolygons: literally ‘many sides’. These shapes can be triangles, hexagons, pentagons… all of those ‘gons’ are polygons. Essentially, anything that has straight sides is called a polygon.Circles are a class onto themselves because they have no straight linesTheir unique characteristics include:Squares have four equal sides and four right anglesRectangles have two pairs of equal sidesA trapezoid has on ly one pair of parallel sidesA trapezium has no sides of equal lengthRhomboids: opposite sides and opposing angles are equalThe isosceles triangle has two equal sidesRight triangles have one 90-degree angle opposite of the hypotenuseEach of these shapes has its own formula to calculate its perimeter, area and angles. Some you may be familiar with, such as the Pythagorean theorem while others are perhaps a bit less memorable.Let’s take a look at them now.Do you need help with your geometry studies? Perhaps you could find a geometry tutor…Calculating TrianglesStarting with the shapes of the fewest sides (but sometimes the most complicated formulas), we tackle geometric formulas head-on!The simplest formula for the perimeter of any triangle is a+b+c, with each letter representing a side. It is beautiful in its simplicity and easy to work with, provided you know each side's length.Let’s say your triangle has these measurements: a = 3 inches, b = 4 inches and c = 5 inchesIts perime ter would then be 3+4+5=12 inches.Clearly, this is a triangle is neither equilateral nor isosceles; nor is it a right triangle. How would we calculate the perimeter if only two values, the bottom and one side, are given?In such a case, we have to draw on Pythagoras’ theorem: a2+b2=c2. You remember that one, right?First, draw a line from the triangle’s peak straight down to its base. This line, h, should be perpendicular to the base, thereby forming two 90-degree angles â€" one on each side of the line.You now have two right triangles, one of which has a measurement for both a and b. From there, it is a simple matter to plug known values into the theorem (don’t forget to square them!) and find your missing value.Let’s try it with a fictitious triangle:a = unknown b = 5 c = 7a2 * 52 = 72a2 * 25 = 49 the unknown value must stand alone on one side of the equationa2 = 49 â€" 25 move 25 to the other side of the equal sign, subtracting it from the given value of ca2 = 24Now you hav e to calculate the square root of 24 to find the value of 'a', which is 4.898. Once you've calculated the perimeter of one right triangle, you must calculate the second to get the dimensions of the original triangle.Congratulations! You now know how to calculate the perimeter of any triangle! This and similar triangles signs are used to urge caution on roadways Image by Gerd Altmann from PixabayCalculating Triangles’ AreaWhile perimeter calculation is a rather simple endeavour, figuring the area of a triangle is a bit more involved.If values are given for all three sides, you may apply Heron’s Formula:area = square root of [s(s-a)(s-b)(s-c)], with 's' being the semi-perimeter, that is (a+b+c)/2It only looks complicated; remember that, when working with a formula, you only need to plug in known values to solve for the unknown. When thought of in that way, the Hero’s Formula, as it is also called, is pretty easy!Now, for ‘area of triangles’ equations where one or more values are unknown.If you know only the value of the triangle’s base and its height, you may apply: area = ( ½) * b * hIf only the length of two sides and the degree of the angle joining them are known, you would use trigonometry to find the missing values. The basic formula is:Area = ( ½) * a * b * sin C Keep in mind that lowercase letters signify line measurements while uppercase letters represent angles.If you only know the values of sides a and c, you would plug them in and calculate sin B. Likewise, if you know b and c, you would employ sin A to get your triangle’s area.Why not practise those for a while before moving on... A=a2 and for rectangles, it is A=l * w. Simple, right?Things start getting complicated when we get into parallelograms and trapezoids; to solve both of those equations, you will need to know the height of the shape (h) an d the length of the base (b) â€" the line at the bottom.Once you know those values, choose the appropriate formula for the shape:b * h = area of parallelograms ( ½)(a+b) * h = area of trapezoids, where  â€˜a’ represents the side opposite of ‘b’.Quadrilaterals may just be the easiest shapes to work with. If you need extra practice, there are plenty of resources online where you can find geometry worksheets and equations to sol ve.Calculating PolygonsWhether you are confronted with an apeirogon (a polygon with an infinite number of sides) or the more familiar hexagon, you need to know how to calculate its perimeter and area.Luckily, apeirogons are only hypothetical; imagine having such a figure to calculate an area for!If your polygon’s sides are all the same length, you can apply P=n * v, where ‘n’ is the number of sides and ‘v’ is the value of each side.If said polygon’s side are not all the same length, you will have to add up those values to get its perimeter. The stop sign is perhaps the most renown regular polygon Image by Walter Knerr from PixabayCalculating Areas of PolygonsThere are several ways to realise the value of any polygon’s area, some of which involve calculations for triangles.First, we tackle the equations for a regular polygon; one whose sides are all the same length. Before we can start any ciphering, we have to determine the polygon’s radius.That involves drawing a circle inside the polygon in such a manner that the circle’s perimeter touches the polygon’s perimeter. This is called an inscribed circle. Once we know that radius’ value, we can apply this formula:A = ½ * p * rFormulae get more complicated the more sides the polygon has.Let’s say the number of sides is represented by ‘n’ and sides by ‘s’. The radius, also called apothem, is designated ‘a’. Of course, ‘A’ represents ‘area’, yielding a formula that looks so:A = ns/4 v 4-s2From here, the formulas get ever more complex. Do they l eave  you struggling with the basics of geometry? You can refer to our complete guide!Calculating CirclesCircles involve neither angles nor lines and their perimeters are called ‘circumference’. However, their calculations do require at least a line segment which is instrumental to any formula for circles.Oddly enough, it seems that the formula for calculating areas of circles is more renown than perhaps for any other geometric shape: pr2, or pi * r2Surely you know/remember that pi (p) has a value of 3.1415...The less-renown formula concerning circles, the one for calculating circumferences is: 2 * p * rBear in mind that these are formulae for calculating the area and perimeter of two-dimensional shapes; once they gain an additional dimension â€" they become 3-D shapes and merit a calculation of volume as well as area and perimeter.Let’s not go off on a tangent, here; we’re quite happy to provide formulas for these basic geometric constructions...But you don’t have to stop here; latch on to our beginner’s guide to geometry!

100 Lesson Plans And Ideas For Teaching Math

100 Lesson Plans And Ideas For Teaching Math Teaching Math is a great process, since it is oriented towards applications and practical thinking. The versatility of a teacher with innumerable innovative ideas on hand paves way for success in teaching Math. Or else, the classes become boring and the teacher could not get across his or her ideas successfully. Why there is a need for 100 Math plans and ideas? It is the basic grasping capability of the targeted students that a teacher needs to keep in mind while preparing for a Math class. When one set of ideas suits the needs of a particular set of students, it could be something else that would appeal to yet another group. So, keeping different ideas in store is always good for a Math teacher, not to run short of the stock in the middle of the class. Hence,there is a necessity for lots of lesson plans and ideas to be stored by a teacher for Math. Here are 100 Math plans and ideas for the benefit of Math teachers. Number System in math Numbers that are not rational are called irrational numbers and students understand that every number has a decimal expansion. Teachers could show how decimal expansion repeats itself with examples. They could make students convert a repeating decimal expansion into a rational number with black board examples. Sounds of PI (Numberphile’s resources) could be an activity to explain the concept. Function Function is a rule and it assigns exactly one output to each input. The graph of the Function is the set off ordered pairs having one input with the corresponding output. Function can be compared to a machine to explain the concept of input and output and the relationship between input and output could be explained in simple tabular columns. An online math tutor could find easy examples for Function like Trigonometry Function to make the students understand the concept easily. 21 Century Lessons: A Boston Teachers Union Initiative offers hand outs and presentations for this lesson. Radicals and Integer Exponents in math Students know and apply the properties of integer exponents for generating equivalent numerical expressions. An activity like gallery walk could motivate students to observe patterns in algebraic expressions.

New Years Resolutions for Kids

New Year’s Resolutions for Kids The school year is well underway, but its a brand new calendar year and an ideal time for students to think about how to continue making positive progress in school. This month, spend time with your child to come up with a set of academic New Years resolutions. This exercise is worthwhile for several reasons: The process of thinking about how to achieve ones goals is highly beneficial, helping students stay motivated, build confidence and persevere. Setting resolutions teaches students how to think introspectively about their life and goals. Taking the time to identify areas of improvement helps students learn the importance of discipline and encourages them to take action to achieve the things they want rather than hope they happen. As you welcome the New Year, here are a few tips for guiding your child to establish resolutions that will kick off the winter term right: Make them realistic. Too often, people make resolutions that are unreachable. Encourage your child to set resolutions that are achievable and reasonable, given your childs age and academic ability. For example, a resolution to earn all As this school year when your child has a C average isnt realistic. A resolution to raise any C grades to a B is more attainable. Focus on the action, not the result. Grades are a useful measure of a students understanding of subject matter and progress toward grade-level standards, but as a parent, try to focus on learning and effort, not outcomes such as grades. When setting resolutions, your childs focus should always be on effort not results. Encourage your child to answer honestly whether he or she is focused on learning class material and has put sincere effort into all subjects. If not, what could your child do differently in the future? Plan out the steps. Setting a goal but failing to define the steps necessary to achieve it is likely to be ineffective. As your child comes up with resolutions, encourage him or her to break down each one into smaller steps. Then, have your child assign dates to each step. Your child should make a plan to follow up on those sub-steps periodically to measure progress. Put it on paper. Its fine to brainstorm resolutions aloud, but always have your child write down the final list. Studies show that people who write down their goals are more likely to achieve them. Committing to resolutions on paper will help your child hone in on exactly what he or she wants to achieve. This written list also serves as inspirationsomething tangible that your child can refer to regularly throughout the remainder of the school year. Incorporate good study habits. No matter who your child is or what age, he or she could likely use a refresher on good study habits, such as time management and organization. Have a conversation with your child about how the year is going so far. Go over the evening schedule and how your child manages time, the homework routine, your childs organizational habits and more. If anything needs improvement, establish resolutions that focus on making changes where needed. Setting New Years resolutions can be very valuable for students going into the second half of the school year, encouraging them to think about what went well and not so well in the fall term and define steps to make adjustments going forward. Youll find that getting your child into the habits of self-reflection and continuous improvement will benefit him or her in the long run as well. Help your child navigate the process so that he or she heads back to school after holiday break armed with a great attitude and a plan for success.

NYU Student Invents Revolutionary Medical Gel Rise of the Accidental Entrepreneur

NYU Student Invents Revolutionary Medical Gel Rise of the Accidental Entrepreneur Andres Rueda/Flickr While most college students are busy discovering the  physics  of beer pong, others are making revolutionary medical breakthroughs. Joe  Landolina, a 20-year old New York University junior has created a lifesaving medical gel  derived  from plant-based polymers which mimic the human  extra-cellular  matrix, a substance produced by the body which  initiates blood clot formation. Landolina has dubbed the substance, Veti-gel. Designed with the purpose to instantly halt bleeding, Veti-gel  bonds to the surrounding flesh and forms a tight seal  upon application. Not only does the gel initiate blood clot formation, but also speeds up the healing process and is effective on major wounds of internal organs and key arteries. Your cells dont fit together cell-to-cell its called an  extra-cellular  matrix, Landolina told the  Metro New York. If you put Veti-Gel into a wound, it recognizes the  existing ECM thats already there and replicates and builds onto it. It instantaneously stops bleeding and is also  biocompatible, so your cells can grow into it and it helps wounds heal faster. Landolina  initially  tested the gel on mice and after slicing their livers and carotid arteries he was  able to  instantly  stop the bleeding. He then began testing on slabs of fresh pork loin  in which  he injected pigs blood; the results of which were so  successful  he recorded a  video  of the experiment and uploaded it on YouTube for the public. In partnership with New York University graduate Isaac Miller, Landolina founded the company  Suneris, Inc.  as a vehicle to shuttle Veti-Gel into the  veterinary  market. For humans there are similar products available, very expensive but similar, but for animals, there is nothing that coagulates blood quickly enough, Landolina explained to  MailOnline, I have spoken to hundreds of vets and heard how in situations where, for example, a spleen is bleeding, they would rather take the spleen out than risk waiting for any of the current products to work quickly enough. So Veti-Gel would be very well received in this industry. Each year more than  140,000 Americans die from trauma-related injuries; excessive blood loss resulting in shock and heart failure are the primary causes for trauma-related deaths.  While Veti-gel is at the moment intended for veterinarian practices, Landolina hopes Veti-Gel will someday be used by the armed forces to treat major trauma victims in the field  and prevent  soldiers  from bleeding out until they can be transported to a hospital. The gel  possesses  antimicrobial properties which mean it’s a safe and disinfecting way to heal a wound, which is especially important for unsanitary war zones. The idea for Veti-Gel came about from a surprising simplistic thought. When I got to NYUs engineering school, I had this idea: What if you could take something that was liquid and turn it solid using chemistry? Landolina told the  Metro New York.  I realized if you could take that and apply it to a bleeding wound; it would turn into a solid mass. I wondered: Could that stop bleeding?”  The trend of the accidental entrepreneur, so to speak, has recently  blossomed  among  college students.  Most recognizably is  Mark Zuckerberg for his founding role in the  revolutionary  social media website Facebook. Rather than  developing  a get rich quick scheme, young entrepreneurs are increasingly achieving success by developing a solution to address a problem theyve experienced personally. The mindset differs between those who build a business around a product rather than building a product around a business. That is how businesses such as  Mint,  Dropbox  and now Suneris, Inc. got their start. With Facebook and Twitter, instantly  promoting  a product to a target audience was never made  simpler, and if technology continues growing in this way, as will the trend of the accidental  entrepreneur.
