Thread: inverse of sine?

Hey guys, I just have a quick question. Is there a true inverse of sine? now I know that an inverse of sine wouldn't be a function, but what if we restricted it. then wouldn't you be able to make a kind-of inverse function?

Ok I i'm just going to come out and say it, can you solve this? (for 'y' of course)

Code:

x=(sqrt(y-2)^2)+(sqrt(-y+4)^2)+sin(y)-2

this question has been eating at my soul for the past few days and if someone could provide some in-site that would be great

-thanks in advance

actually I need it for x=0 to try to find Pi so in that case you can just solve this...

Code:

0=(sqrt(y-2)^2)+(sqrt(-y+4)^2)+sin(y)-2

God... that's ugly.

-thanks again

btw: my logic has been all over the place lately so if something looks strange, that's why. like if i am using Pi to find Pi, that's what my friend told me I am doing...
