Trigonometric Functions Calculator

OPTIONS

Sides involved in the function

Sine - sin(x) - opposite/hypotenuse

Cosecant - csc(x) - 1/sin, hypotenuse/opposite

Inverse sine - arcsin(x), asin(x) - sin(arcsin(x)) = arcsin(sin(x)) = x

Inverse cosecant - arccsc(x), acsc(x) - csc(arccsc(x)) = arccsc(csc(x)) = x

Unit

Number of decimal places (round)

What are Trigonometric Functions

Trigonometric functions are mathematical functions that relate angles to ratios of sides in right triangles. They include sine, cosine, tangent, and their reciprocals (cosecant, secant, cotangent) plus inverse functions. These are fundamental in mathematics, physics, engineering, and computer graphics for analyzing periodic phenomena, waves, rotations, and geometric relationships.

What is Online Trigonometric Functions Calculator

An online trigonometric functions calculator is a web-based tool that computes trigonometric ratios and their inverses without downloading software. It supports both degrees and radians, calculates all six basic trigonometric functions plus their inverses, includes special functions like atan2, and provides customizable precision for educational, scientific, and engineering applications.

How to Calculate Trigonometric Functions

Select the function type (sine/cosine/tangent group), enter the input values for the desired functions, choose your preferred unit (degrees or radians), set the number of decimal places for precision, and the tool will automatically calculate and display all related trigonometric functions with their formulas and results highlighted in green.
