Excel ASINH Function allows you to calculate the inverse hyperbolic sine of a given number. In simpler terms, it helps you find the value whose hyperbolic sine is equal to the specified number. This function can be handy in various mathematical and scientific calculations.

## Syntax

**ASINH(number)**

## Arguments

number | The number for which you want to find the inverse hyperbolic sine. It should be a real number. |

## How to use

You can use the ASINH function in Excel by following this simple syntax:

1 |
=ASINH(number) |

Here’s a step-by-step guide on how to use it:

- Select the cell where you want the result to appear.
- Type the formula, starting with the equal sign (=).
- Inside the parentheses, enter the number for which you want to find the inverse hyperbolic sine.
- Press Enter to calculate the result.

## Examples

Let’s look at a few examples to understand how to use the ASINH function:

**Example 1:** Calculate the inverse hyperbolic sine of 2.5

1 |
=ASINH(2.5) |

The result will be approximately 1.64723.

**Example 2:** Find the inverse hyperbolic sine of -1.3

1 |
=ASINH(-1.3) |

The result will be approximately -1.19302.

**Example 3 (Optional):** Using a cell reference

If you have the number in a cell, say A1, you can use a formula like this:

1 |
=ASINH(A1) |

## Additional information

The ASINH function is part of Excel’s trigonometric functions and is mainly used in mathematical and scientific calculations. It operates on real numbers and returns a real number as the result.
