hey, I'm new so I hope I am doing this right.

I missed some class so I'm kind of unsure how to solve some problems that are due tomorrow.

1) csc (pie/3) and I have to find the exact value. I wasn't sure if I just put that all under 1 and use sin or what.

2) sin(-300 degrees)...I got square root 3/2...I have no idea if that's correct

3) sec (-510 degrees)

thanks for any help!
