Right Triangle Trig Ratios for Visual and Kinesthetic learners
The notes that come with this graphic provide detailed steps for teaching the vocabulary of "hypotenuse," "opposite" and "adjacent" sides in right triangles. This vocabulary provides the basis for the rest of the notes about trig ratio definitions (sine, cosine, and tangent). The techniques are designed for visual and kinesthetic learners. This method easily shows why the sine of one acute angle is equal to the cosine of the complementary angle.
There is one page of notes and six pages of grap

TRIGONOMETRY: THE REFERENCE TRIANGLE AND THE REFERENCE ANGLE
One of the most confusing topics to students when teaching trigonometry is the concept of reference angles and triangles. Many books do not tie this concept holistically so that students can understand how to compute the reference angle of any angle and also to come up with the reference triangle for that angle.This e-book will give both the teachers and the students the exact ideas that must be used to compute the reference angle of any angle. The first part of this e-book shows how to label th

TRIGONOMETRY: PROVING TRIGONOMETRIC IDENTITIES
How to prove Trigonometric Identities An identity is an equation that is known to be always true.To prove a trigonometric identity follow these suggested guidelines:1. Pick a side that is easy to transform. Pick the left-hand side (LHS) or the right-hand side (RHS)2. Use algebra or basic trigonometric identities to transform one side to another.3. If it is possible, express the entire equation in terms of one trigonometric function4. If it is possible, express the side chosen in terms of sine an

TRIGONOMETRY: HOW TO FIND SIX TRIGONOMETRIC RATIOS
In this article, I describe some very simple steps that can be used by any student to find all the six trigonometric ratios for special angles.The angles are 0, 30, 45, 60 and 90 degrees. The angles can also be given in radians.Our method can augment the unit circle very well. The method described is rarely taught in schools but very useful!

Trigonometric Pythagorean Identities
This video demonstrates how to establish the Trigonometric Pythagorean Identities.The Pythagorean trigonometric identity also called simply the Pythagorean identity, is an identity that expresses the Pythagorean theorem in terms of trigonometric functions such as sine, cosine, tangent, cotangent, cosecant, and secant.
