You can put this solution on YOUR website! how do i evaluate Arcsin(-1)? with no calculator
------
You have to know that Arcsin(-1) means "the angle
whose sine is -1".
---
Then you have to know that sine is -1 when the
angle is 270 degrees or (3/2)pi radians.
----
If you know both of those things, you know the
answer to your problem is arcsin(-1) = 270 degrees.
