# IMCOS

Formulas / IMCOS
Calculate the complex cosine of a complex number.
`IMCOS(inumber)`
• inumber - required complex number used to get the cosine of the complex number

## Examples

• `=IMCOS(A2)`

This will return the complex cosine of the number in cell A2.

• `=IMCOS(A2+B2)`

This will return the complex cosine of the sum of the numbers in cells A2 and B2.

• `=IMCOS("Hello")`

This will return the complex cosine of the text â€œHelloâ€.

## Summary

The IMCOS function is a tool for calculating the complex cosine of a complex number, and is conveniently compatible with Sourcetable.

• The IMCOS function takes a complex number as an input and calculates the complex cosine of that number.
• The IMCOS function uses both the real and imaginary parts of the input number to calculate the complex cosine.

## Frequently Asked Questions

What is the IMCOS function?
The IMCOS function calculates the cosine of a complex number. It takes a complex number as its argument and returns an error value if the number is a logical value.
How does the IMCOS function work?
The IMCOS function takes a complex number as its argument and converts the real and imaginary coefficients into a complex number. Then it calculates the cosine of that complex number.
What kind of argument does the IMCOS function take?
The IMCOS function takes a complex number as its argument.
What is the output of the IMCOS function?
The IMCOS function returns the cosine of the complex number.
What happens if the argument is a logical value?
The IMCOS function returns an error value if the argument is a logical value.
