Inverse Right Triangle Trigonometry
By kthomp271828
Inverse trig functions are used to find missing angles rather than missing sides. This video explains how to use inverse trig to find a missing angle.
Area of a Triangle - MathHelp.com - Geometry Help
By yourteachermathhelp
Students learn the formula for the area of a triangle and are asked to solve problems using this formula. Note that right triangle formulas and trigonometry are used extensively in the problems in this lesson.
45-45-90 triangles | Right triangles and trigonometry | Geometry | Khan Academy
By Khan Academy
Video uses an electronic black board with different colored pens. Introduction to 45-45-90 Triangles, these can also be called right triangles because of the 90 degree measurement. These triangles are special because if two angles of a triangle are equal the one side they don’t share is going to be equal. This then goes on to explain Pythagorean Theorem, Side A squared + Side B squared = Side C squared, side C is the hypotenuse or the side that is shared in a triangle. The narrator goes on to explain how to solve, using square roots. This video is for middle school students.

Trigonometric Substitution
By The Organic Chemistry Tutor
This calculus video tutorial provides a basic introduction into trigonometric substitution. It explains when to substitute x with sin, cos, or sec. It also explains how to perform a change of variables using u-substitution integration techniques and how to use right triangle trigonometry with sohcahtoa to convert back from angles in the form of theta to an x variable. There's plenty of examples and practice problems in this lesson.
