# How do you find the inverse of sin?

##### 1 Answer

The inverse of the

But sine itself, would not be invertible because it's not injective, so it's not bijective (invertible).

To obtain arcsine function we have to restrict the domain of sine to

For example:

Since

If you meant by your question "how do you calculate the value of the

then the answer is that there is no easy way to do this (with the exception of a few special values) just as there is no easy way to calculate the value of
