Function: =ASIN()
The ASIN function in Excel returns the arcsine (inverse sine) of a given number in radians. The function can be used to find the angle whose sine value is equal to the given number.
How to use ASIN() in excel:
To use the ASIN function, simply enter “=ASIN(number)” into a cell, where “number” is the value for which you want to find the arcsine. The function will return the result in radians.
To use the ASIN function in Excel, follow these steps:
- Select the cell where you want to display the result.
- Type the following formula into the formula bar: =ASIN(number), where “number” is the value for which you want to find the arcsine.
- Press Enter to calculate the result.
- The result will be displayed in the selected cell.
For example, if you want to find the arcsine of 0.5, you would enter “=ASIN(0.5)” into a cell. Excel will calculate the result in radians and display it in the cell.
Note that the input value for the ASIN function should be between -1 and 1. If the input value is outside this range, Excel will return the #NUM! error. Also, the result of the ASIN function is given in radians, which is a unit of measurement for angles. If you want to convert the result to degrees, you can use the DEGREES function.
Examples ASIN() function in excel formulas:
- =ASIN(0.5) returns 0.523598776 radians (which is approximately 30 degrees).
- =ASIN(-0.5) returns -0.523598776 radians (which is approximately -30 degrees).
- =ASIN(1) returns 1.570796327 radians (which is approximately 90 degrees).
- =ASIN(0) returns 0 radians (since the sine of 0 is also 0).
- =ASIN(2) returns #NUM! (since the sine of any value is always between -1 and 1).
List of similar functions:
- SIN: returns the sine of an angle in radians.
- COS: returns the cosine of an angle in radians.
- TAN: returns the tangent of an angle in radians.
- ACOS: returns the arccosine (inverse cosine) of a given number in radians.
- ATAN: returns the arctangent (inverse tangent) of a given number in radians.
