The Distance Formula: How to calculate the distance between two points. YouTube Lesson, interactive demonstration, with practice worksheet. Tangram Constructions Fun. Bridge Constructor. Honors Geometry - docslide. GCSE Bitesize - Geometry and measures. Teaching trigonometry via problem solving - Mathematics for Teaching. I believe that the best way to learn mathematics is through solving problems.
However, most problems are found at the end of unit or chapters. Because we are in a hurry to cover the textbooks or the curriculum, we skip the problem solving part and then we complain that our students are very poor in problem solving. The only way to develop problem solving skills is by solving problems.
The only way not to skip problem solving is to put it in the beginning of the lessons, use it in teaching the concept than as applications after learning the concepts only. I have shared sample lessons on teaching integers and algebraic expressions via problem solving in this blog. Features of the lesson Teaches via problem solvingThe problems have many solutionsLinks new concepts to previously learned knowledgeProblems are in real-life contextsShows geometric and algebraic (function) side of trigonometryStudents compares and evaluates different solutions.
Finding the Distance Between Two Points. By kirupa | 13 January 2011 (revised on 17 January 2011) Have questions?
Discuss this Flash / ActionScript tutorial with others on the forums. There will be times when you need to know how far apart two items are. While it is common in games or situations involving collision detection, you will run into needing to know the distance more often than you think. For example, the Random Movement animation is a case where the distance between two points is used to gauge when to change direction: In this short tutorial, you will learn how to use the Pythagorean Theorem to calculate the distance when you know the x and y coordinates of two points. A full explanation and more about the Pythagorean Theorem can be found on Wikipedia, but in a nutshell, the equation looks as follows: Your distance is the square root of the net horizontal distance squared and your net vertical distance squared.
The code for converting our equation into the ActionScript that Flash understands is as follows: Need Help? Web.spu.ac.th/sdm/files/2012/07/03-Trigonometry-for-Animation.pdf. Animated Trigonometry. Computer Science. Branching Out — The Obvious Collection. Math247.
Precalc_Trigonometric Functions.html. Lesson 1 2. 1. Graphs of y = a sin x and y = a cos x. By M. Bourne The Sine Curve y = a sin t The sine curve occurs naturally when we are examining waves. When waves have more energy, they go up and down more vigorously. We say they have greater amplitude. Let's investigate the shape of the curve y = a sin t and see what the concept of "amplitude" means. Have a play with the following interactive. Sine curve Interactive Run the animation first (click "Start"). You can also drag the dot around the circle to create a sine curve (do it slowly). The scale for this is radians. T = θ = 0 y = 100 sin(0) = 0 Amplitude = radius = 100.0 2π π 23π 2π t fps = 0 Copyright © www.intmath.com Did you notice? The shape of the sine curve forms a regular pattern (the curve repeats after the wheel has gone around once).
