CSC
TheCSC
function returns the cosecant of an angle. The cosecant is the reciprocal of the sine function. It takes an angle in radians as its only argument.

Usage
Use the CSC
formula with the syntax shown below, it has 1 required parameter:
 angle (required):
The angle in radians for which to calculate the cosecant. Must be a numeric value or a reference to a cell containing a numeric value.
Examples
Here are a few example use cases that explain how to use theCSC
formula in Google Sheets.
Calculating the cosecant of an angle
One common use of the CSC
function is to calculate the cosecant of an angle. For example, you may need to find the length of the hypotenuse of a right triangle given the length of the adjacent side and the angle opposite that side. You can use the cosecant function to find the length of the hypotenuse.
Calculating the distance between two points
Another use of the CSC
function is to calculate the distance between two points on a circle. If you know the radius of the circle and the angle between the two points, you can use the cosecant function to find the distance between them.
Common Mistakes
CSC
not working? Here are some common mistakes people make when using the CSC
Google Sheets Formula:
Using degrees instead of radians as input
The CSC
function requires the input angle to be in radians, not degrees. You can convert degrees to radians using the RADIANS
function. For example, to calculate the cosecant of 45 degrees, you should use =CSC(RADIANS(45))
, not =CSC(45)
.
Dividing by zero
The CSC
function returns an error if the input angle is a multiple of π. This is because the cosecant of these angles is undefined, which means that the function would be dividing by zero. To avoid this error, you can add a small value to the input angle, such as 0.0001, to make it slightly different from a multiple of π.
Related Formulas
The following functions are similar to CSC
or are often used with it in a formula:

SIN
The
SIN
function in Google Sheets returns the sine of a given angle in radians. Sine is a mathematical function that describes a smooth repetitive oscillation. It is commonly used in trigonometry, physics, and engineering to model phenomena such as waves, oscillations, and periodic motion. 
COS
The
COS
function in Google Sheets returns the cosine of an angle provided in radians. It is commonly used in trigonometry to calculate the cosine of an angle. The function takes one parameter, the angle in radians. 
TAN
The
TAN
function returns the tangent of an angle specified in radians. Tangent is the ratio of the length of the opposite side to the length of the adjacent side of a rightangled triangle. This function is commonly used in trigonometry and geometry calculations.
