The Trigonometric Identities we introduced the(Sines, Cosines and Tangents). We begin by reminding ourselves of the 2X + Cos2X = 1 In addition, there are relations called: Sin 2X = 2 Sin X Cos X Cos 2X = Cos2X - Sin2X Because SinX + CosX = 1, this last relation can also be ...
For example, some trigonometric identities or formulas that are helpful when dealing with finding trigonometric functions of large angles are as follows: $$\begin{align*} \sin \left( {360 + \theta } \right) &= \sin \left( \theta \right)\\ \cos \left( {360 + \theta } \right) &=...
I want to prove the trig identities sin(−θ)=−sin(θ)sin(−θ)=−sin(θ) and that cos(−θ)=cos(θ)cos(−θ)=cos(θ). I realize I can prove it by drawing out the radius when it is rotated by θθ, and the radius when it is rotated by −θ...
