WebProving Trigonometric Identities - Basic. Trigonometric identities are equalities involving trigonometric functions. An example of a trigonometric identity is. \sin^2 \theta + \cos^2 \theta = 1. sin2 θ+cos2 θ = 1. In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities. WebDec 20, 2024 · The cosecant function is therefore odd. Finally, the secant function is the reciprocal of the cosine function, and the secant of a negative angle is interpreted as sec( − θ) = 1 cos( − θ) = 1 cosθ = secθ. The secant function is therefore even. To sum up, only two of the trigonometric functions, cosine and secant, are even.
