In this sections A, B, C denote the three (interior) angles of a triangle, and a, b, c denote the lengths of the respective opposite edges. They are related by various formulas, which are named by the trigonometric functions they involve. The law of sines states that for an arbitrary triangle with sides a, b, and c and angles opposite those sides A, B and C:

As we know, tan is the ratio of sin and cos, such as tan θ = sin θ/cos θ. Thus, we can get the values of tan ratio for the specific angles. Sin Values. sin 0° = √(0/4) = 0. sin 30° = √(1/4) = ½. sin 45° = √(2/4) = 1/√2. sin 60° = √3/4 = √3/2. sin 90° = √(4/4) = 1. Cos Values. cos 0° = √(4/4) = 1. cos 30° = √(3/4) = √3/2

sin (2π + A) = sin A & cos (2π + A) = cos A. All trigonometric identities are cyclic in nature. They repeat themselves after this periodicity constant. This periodicity constant is different for different trigonometric identities. tan 45° = tan 225° but this is true for cos 45° and cos 225°.
