I have a quiz tomorrow, i need someone to explain how to do this.
sin-1(sin 10?/7 )
To make it clear its the Inverse sin of sin of ten pi over 7.
I understand that it's not in range of [- ?/2 , ?/2 ]
Somehow the answer is -3?/7 How do you get to this? I'm really confused. Do i subtract something or what??
Also it has to be exact answer using pi.. no decimals.. Please help!
