[-pi/2, pi/2]
because if you go further anymore to the Right it will case a repeat in y-values
[-1,1] |

sin(sin-1 pi/2) = pi/2
defined, why? |
|
Definition
No, Because pi/2 is greater then x=[-1,1]
inverse sin remember |
|
|
Term
|
Definition
| sin -pi/2, because remember sin can only have a range of [-pi/2, pi/2]. and since 3pi/2 is beyond this point we can find the range b/w restricted area by subtracting by 2pi to get back to the orgin |
