Enter any angle into the cosecant calculator. The calculator will display the result of that cosecant, also known as 1/sine(x).

Cosecant Formula

The following formula is used to calculate the value of a cosecant of an angle.

CSC(x) = 1/sin(x)

  • Where CSC is the cosecant
  • x is the angle in degrees or radians

As you can see from the equation above, the cosecant is equal to 1 divided by the sin of the same angle.

Cosecant Definition

A cosecant is defined as the inverse value of the sine of a value.

How to calculate cosecant?

How to calculate cosecant

  1. Determine the angle you wish to evaluate

    Calculate or measure the angle to take the cosecant.

  2. Take the sin of the angle

    Take the sine value of that angle.

  3. Calculate the cosecant

    Divide 1 by the sine value calculated in step 2 to determine the cosecant.
