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.

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 …

The meaning of TRIG is trigonometry. How to use trig in a sentence.

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

We have certain formulas to find the values of the trig functions using the sides of a right-angled triangle. To write these formulas, we use the abbreviated form of these functions.
