WebMay 9, 2024 · The Pythagorean identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan( − θ) = − tanθ. cot( − θ) = − cotθ. WebLet us see the applications of the double angle formulas in the section below. Examples Using Double Angle Formulas. Example 1: If tan A = 3 / 4, find the values of sin 2A, cos 2A, and tan 2A. Solution: Since the value of tan A is given, we use the double angle formulas for finding each of sin 2A, cos 2A, and tan 2A in terms of tan.
