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.
