ARC means the angle..
arcsin means the angle whose sine is ...x

arccos means the angle whose cosine is ..

Answered by Malisa
so, for this problem, the range is -1 to 1?
Answered by bobpursley
y is the angle. Wouldn't it range from -inf to + inf? (4n+1)*PI/2 for all n ?

check my thinking.
Answered by Malisa
I still don't get it. How come y is the angle?
Answered by bobpursley
The original equation, I read:

y is the angle whose sine is x
y=arcsin x
