Trigonometric identities refer to equations involving trigonometric functions which are true for any angle value. The following are some examples: Cosine Double-Angle Identities: cos2x=cos2x−sin2x cos2x=2cos2x−1 cos2x=1−2sin2x ...
the integral of sin^2(x) should equal -cos^2(x); in fact, the answer does not contain a cosine at all. You cannot directly integrate sin^2(x). Use trigonometric identities and calculus substitution
{eq}\sin x^2 = \sin^2 x {/eq} Trigonometric Identity: A trigonometric identity is a special class of trigonometric expression. Trigonometric identities are generally true for any angle. One way to distinguish a regular trigonometric expression from an identity is by l...
