The IMCOSH function returns the hyperbolic cosecant of a complex number in rectangular notation.


Use the IMCOSH formula with the syntax shown below, it has 1 required parameter:

  1. number (required):
    The complex number for which to calculate the hyperbolic cosecant. The number can be provided as a real or imaginary number, or in x + yi or x + yj format.


Here are a few example use cases that explain how to use the IMCOSH formula in Google Sheets.

Calculate hyperbolic cosecant of a complex number

This function can be used to calculate the hyperbolic cosecant of a complex number in rectangular notation.

Perform engineering calculations

The IMCOSH function is part of the Engineering category of functions in Google Sheets and can be used to perform various engineering calculations.

Common Mistakes

IMCOSH not working? Here are some common mistakes people make when using the IMCOSH Google Sheets Formula:

Using the Wrong Input Format

One common mistake when using the IMCOSH formula is providing an input in the wrong format. The input must be a complex number in the form of a + bi.

Confusing Hyperbolic Cosine with Other Functions

Another common mistake is confusing the IMCOSH function with other trigonometric or hyperbolic functions.

The following functions are similar to IMCOSH or are often used with it in a formula:


    The IMSINH function calculates the inverse hyperbolic sine of a given complex number. Inverse hyperbolic sine of a complex number is the value whose hyperbolic sine is the given complex number. This function is useful in engineering applications that involve complex numbers.


    Calculates the inverse of the tangent of a number in radians. The resulting angle is returned in radians. This function is most commonly used in engineering calculations that involve angular measurements.
