First time posting, hey guys!
I need urgent h/w help that's due tomorrow.
Here are the problems:
2cosxcscx - 4cosx - cscx + 2 (find all the answers in the intervals of 0 to 2pi)
5sin^23x + 8sin3x - 4
(i finally was able to factor this and then i don't know how to solve the equations from there)
sec^2xtan^2x + sec^2x = sec^4x
(verify identity i think)
LAST EDIT: i figured out the third one! :)
