sin(1) = 90

Question

If I want to use in the Math.sin(1) = 90
Not 90 = 1
And in the cos or tan

Answer 1

The trigonometric functions return the result in radians. If you want degrees, you have to convert it like this:
window.alert(Math.round(Math.asin(1)*57.2957795))

Answer 2

You need something like Math.asin(1.0)*(180.0/Math.PI)

Answer 3

Are you trying to convert radians to degrees?
