# ASIN

## Y ## What is ASIN?

ASIN is a DAX function in Power BI that returns the arcsine of a given number. In simpler terms, the function returns the angle whose sine is a specified number. The ASIN function takes one argument, which is the number whose arcsine you want to find. The argument should be between -1 and 1.

## Syntax

The syntax for the ASIN function is as follows:

``` ASIN(number) ```

Where number is the argument for which you want to find the arcsine.

## Example

Suppose you have a dataset that contains the following information:

| Salesperson | Sales |

| ———– | —– |

| John | 100 |

| Jane | 200 |

| Mark | 150 |

| Paul | 300 |

You want to find the arcsine of the sales made by each salesperson. To do this, you can use the ASIN function as follows:

``` =ASIN(Sales/1000) ```

This will return the arcsine of the sales made by each salesperson divided by 1000.

## Importance of ASIN

The ASIN function is particularly useful in trigonometry and for calculating angles. In Power BI, you can use the ASIN function to perform various calculations, such as calculating the angle from the sine of a given number. This function can also be used to calculate the inverse sine of a number, which can be helpful in many data analysis scenarios.

The ASIN function is a powerful tool in Power BI that can help you perform complex calculations and data analysis. It is particularly useful for trigonometric calculations and for finding angles. In this article, we discussed the syntax and usage of the ASIN function in Power BI. By using this function in your data analysis, you can gain valuable insights and make informed business decisions.
