# IMSINH

Formulas / IMSINH
Calculate the hyperbolic sine of a complex number.
`IMSINH(inumber)`
• inumber - required, complex number

## Examples

• `=IMSINH("4+3i")`

The function returns the inverse hyperbolic sine of a complex number. For example, the formula returns the inverse hyperbolic sine of 4+3i, which is 1.76274717403908.

• `=IMSINH(5)`

The function can also be used to calculate the inverse hyperbolic sine of a real number. The formula returns the inverse hyperbolic sine of 5, which is 3.62686040784701.

• `=IMSINH(SINH(5))`

The function can be used in combination with other Sourcetable functions. For example, the formula returns the inverse hyperbolic sine of the hyperbolic sine of 5, which is 5.

• `=IMSINH(A1:A3)`

The function can also be used to calculate the inverse hyperbolic sine of a range of cells. For example, the formula returns the inverse hyperbolic sine of the values in cells A1, A2 and A3.

What is the IMSINH function?
The IMSINH function is a mathematical function that calculates the hyperbolic sine for a complex number. It takes a complex number as an argument, which must be in x+yi or x+yj text format.
What does the IMSINH function return?
The IMSINH function returns the hyperbolic sine of the complex number.
What is the format of the complex number?
The complex number must be in x+yi or x+yj text format.
What happens if the argument is a logical value?
The IMSINH function returns an error if the argument is a logical value.
