The CSC function in Excel calculates and returns the cosecant of a given radians. Cosecant is reciprocal of sine .
COSEC(θ) = Hypotenuse / Opposite = c/a
Cosecant of the angle θ, is the ratio of the hypotenuse side – c to the opposite side -a.
Syntax of CSC Function in Excel
Where Argument number is angle in radians which you need to calculate the cosecant of.
NOTE: If your angle is in degrees, you will need to convert it into radians before supplying it to the CSC Function with the help of Radians function
=RADIANS( degrees )
Example of CSC Function in Excel
- In Row number 2 and 3 the radians value is passed to the CSC Function
- In row number 4, Angle 60 degree is converted to radians and passed as input to the CSC Function.
- In Row number 5 Radians -π/6 is passed as input to the CSC Function.
- In row number 6, Angle -90 degree is converted to radians and passed as input to the CSC Function.
