CSS types.asin() Function
The inverse sine of an integer between -1 and 1 is returned by the trigonometric asin() CSS function. The single computation in the function yields the number of radians that correspond to an angle between -90deg and 90deg.
Syntax:
/* numeric values */
transform: rotate(asin(-0.9));
transform: rotate(asin(1));
/* Other values */
transform: rotate(asin(pi / 2));
transform: rotate(asin(e / 4));
Parameter: This function accepts a single parameter:
- number: This is the numeric value translated from -1 to 1.
Return Value: It will return an angle for the inverse sine of a number that will lie in between -90deg and 90deg.
- The result will be NaN if the number is less than -1 or greater than 1.
- The result will be 0⁻ if the number is 0⁻.
Example 1: This example describes how the asin() function works.
HTML
<!DOCTYPE html>
< html lang = "en" >
< head >
< style >
div.heading {
width: 100px;
height: 30px;
color: green;
padding: 30px;
}
div.heading-1 {
transform: rotate(asin(0.1));
}
div.heading-2 {
transform: rotate(asin(0.2));
}
div.heading-3 {
transform: rotate(asin(1));
}
div.heading-4 {
transform: rotate(asin(-0.2));
}
div.heading-5 {
transform: rotate(asin(-0.1));
}
</ style >
</ head >
< body >

< div class = "heading heading-3" >

Example 2: This is another example to understand how the asin() function works using pi and e values.
HTML
<!DOCTYPE html>
< html lang = "en" >
< head >
< style >
div.heading {
width: 100px;
height: 30px;
color: green;
padding: 30px;
}
div.heading-1 {
transform: rotate(asin(pi/8));
}
div.heading-2 {
transform: rotate(asin(e/5));
}
</ style >
</ head >
< body >
< h1 >GeeksforGeeks</ h1 >
< h2 >asin() function</ h2 >
< div class = "heading heading-1" >
GeeksforGeeks
</ div >
< div class = "heading heading-2" >
GeeksforGeeks
</ div >
</ body >
</ html >
