Sorry to post another topic, but i thought this would be easy to find on google, to help me with , but i cant find it. All im really lookin for is someone to let me know if my answers are right, and if not, then how i can fix them Anyways, i was asked to graph y=sin(arsinc) So i graphed the line y=x with the doman as -1 to 1 and the range as -pi/2 to pi/2 Then i neded to graph y=arsin(sinx) So i graphed the line y=x with the domain as -pi/2 to pi/2 and the range as -1 to 1 This is just wat i came up with based on my profs notes, but im not sure if they are right, or even how i came up with them. I just tried a few things and thought this made sense. haha if someone could let me know if this is right, i'd greatly appreciate it !
