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!
