You can put this solution on YOUR website!
Just present the problem with a thank you.
Telling us that you don't have the slightest clue doesn't help solve the problem.
It just makes me wonder "Where was this person during class?"
Everyone here really needs help.
The key to this problem is trig identities.
Gather up all the trig identities that you can find especially those with sin^2 and tangent ^2 or cotangent ^2
PS Don't use x for multiplication when you also use x for an unknown.
