How to use COT Google Sheets formula?

The syntax for the COT formula is =COT(angle), it has 1 required parameter.

COT

The COT function returns the cotangent of an angle specified in radians. The cotangent is the ratio of the adjacent side of a right-angled triangle to the opposite side, and is the reciprocal of the tangent.

Parameters:

angle (required):
The angle in radians for which to return the cotangent. Must be a numeric value.

Examples

Here are a few example use cases that explain how to use the COT 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 right-angled triangle

Use COT along with the length of the opposite side of a right-angled triangle to calculate the length of the adjacent side.

Determine the phase shift of a trigonometric function

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 non-numeric value, the formula will return an error. Make sure to provide a valid angle value.

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 right-angled 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.
