A **trigonometry calculator** is a function used to solve the properties of right triangles in terms of angles, sides, and distances in mathematics. Including the main trigonometric functions are sin, cos, tan, cot.

In which, the functions are determined as follows:

sin A = opposite / hypotenuse = a / c

cos A = adjacent / hypotenuse = b / c

tan A = opposite / adjacent = a / b

cot A = adjacent / opposite = b / a

*How to use:*

Enter the value of sin, cos, or tan.. then click "Calculate". The exact results will be returned to you.

This tool is very easy to use and smart.
