Examples
Here are a few example use cases that explain how to use theCOT
formula in Google Sheets.
Calculate the cotangent of an angle
Use COT
to calculate the cotangent of a given angle, which can be useful in trigonometry or geometry calculations.
Find the length of an adjacent side of a rightangled triangle
Use COT
along with the length of the opposite side of a rightangled triangle to calculate the length of the adjacent side.

Use COT
in conjunction with other trigonometric functions to determine the phase shift of a sinusoidal function.
Common Mistakes
COT
not working? Here are some common mistakes people make when using the COT
Google Sheets Formula:
Using degrees instead of radians
The COT
formula requires the angle to be provided in radians. If you accidentally provide the angle in degrees, the result will be incorrect. To convert degrees to radians, use the RADIANS
formula.
Not providing a numeric angle value
The COT
formula requires the angle value to be numeric. If you provide a nonnumeric value, the formula will return an error. Make sure to provide a valid angle value.
Related Formulas
The following functions are similar to COT
or are often used with it in a formula:

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. 
CSC
The
CSC
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. 
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.
