Trigonometry is known for its many identities. These trigonometric identities [5] are commonly used for rewriting trigonometrical expressions with the aim to simplify an expression, to find a more useful …

Trigonometry helps us find angles and distances, is used a lot in science, engineering, video games, and more! The triangle of most interest is the right-angled triangle. The right angle is shown by the …

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 …

This trig calculator finds the values of trig functions and solves right triangles using trigonometry.

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.

It covers trigonometric ratios such as sine, cosine, and tangent. It explains how to evaluate it using right triangle trigonometry and SOHCAHTOA. In addition, it explains how to solve the missing...
