What is Meant by Trig Function?

In mathematics, trigonometry is a branch that deals with the study of angles and sides of a right triangle. Based on the sides and the angles, the trigonometric functions can be classified into six types, namely sine, cosine, tangent, cosecant, secant and cotangent. The trigonometric ratios of these six functions are given below

Sine Function = Opposite Side / Hypotenuse

Cosine Function = Adjacent Side/ Hypotenuse

Tangent Function = Opposite Side/Adjacent Side

Cosecant Function = Hypotenuse/Opposite Side

Secant Function = Hypotenuse / Adjacent Side

Cotangent Function = Adjacent Side/ Opposite Side

On this page is a trigonometric functions calculator, which calculates the result for a given input angle for the 6 trigonometric functions – sine, cosine, tangent, cotangent, secant, and cosecant.

Using the Trigonometric Functions Calculator

To use the tool to find the results of the trigonometric functions for a given angle, enter the angle, choose how its measured (degrees or radians) and compute.

  • Angle: Enter the angle which you'd like to compute the functions using
  • Degrees or Radians: Choose which units you use to measure the angle

Where results are undefined, you'll see "NaN".

What are the trigonometric functions?

The trigonometric functions, which are defined in terms of the unit circle – or, for angles under 90 degrees (square), alternatively defined using a right triangle.

In terms of the right triangle, the functions are defined as:

  • sine: opposite/hypotenuse
  • cosine: adjacent/hypotenuse
  • tangent: opposite/adjacent
  • cotangent: adjacent/opposite
  • secant: hypotenuse/adjacent
  • cosecant: hypotenuse/opposite

If you know the result of one of the trigonometric functions already, you can reverse it into an angle using the inverse trigonometry functions calculator.
