WebSum, difference, and double angle formulas for tangent. The half angle formulas. The ones for sine and cosine take the positive or negative square root depending on the quadrant of the angle θ /2. For example, if θ /2 is an acute angle, then the positive root would be used. Truly obscure identities. These are just here for perversity. Web26 Mar 2016 · When a square root appears inside a trigonometric identity, and you know both sides are equal, you have to square both sides at some point to finish the proof. However, if you don't know both sides are equal, you have to start with one side and attempt to get it equal to the other side. For example, say you have to prove.
