take the arcsine of a number in javascript

To take the arcsine of a number in JavaScript, you can use the Math.asin() method. This method returns the arcsine of a number in radians.

Here's an example code snippet:

index.tsx
const num = 0.5;
const arcsine = Math.asin(num); // returns 0.5235987755982989 (in radians)
92 chars
3 lines

In this example, we're taking the arcsine of 0.5. The result is 0.5235987755982989 radians, which is approximately 30 degrees.

Note that the input to Math.asin() should be a number between -1 and 1. If the input is outside of this range, the method will return NaN (Not a Number).
