Dec 12, 2025 · There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant …

Trigonometric functions are also called circular functions. The table below shows the six trigonometric function values for the specified angles in both degrees and radians.

Periods of the Trig Functions The period of a function is the number, T, such that f ( +T ) = f ( ) . So, if ! is a xed number and is any angle we have the following periods.

Basic trig identities are formulas for angle sums, differences, products, and quotients; and they let you find exact values for trig expressions.
