The trig ratios are the basis for the study of trigonometry, which literally means "the measuring of angles and sides of triangles" in Greek. Here are the three ratios from which all other identities are found. The reader should be familiar with these three ratios. $$\sin\theta=\frac{\te...

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 ...
