The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions. The remaining trigonometric functions secant sec , cosecant csc , and cotangent cot are defined as the reciprocal functions of cosine, sine, and tangent, respectively. Trigonometric identities are equations involving the trigonometric functions that are true for every value of the variables involved. Periodicity of trig functions. Identities for negative angles. Sine, tangent, cotangent, and cosecant are odd functions while cosine and secant are even functions. Key Questions What does it mean to prove a trigonometric identity?

Make the expression negative because sine is negative in the fourth quadrant. I still don't see a limit and I still don't understand how a limit at infinity can exist.

In trigonometry , trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities , which are identities potentially involving angles but also involving side lengths or other lengths of a triangle.
