I just don't get this stuff. I've been trying on my own with the book. Also, is there a better way to post this? 1. The problem statement, all variables and given/known data tanx 1 + secx _________ + _________ = 2csc x 1 + secx tanx I need to prove that this side equals the other. 2. Relevant equations http://users.rcn.com/mwhitney.massed/trigresources/trig-reference.html [Broken] ^^The reference I was using. 3. The attempt at a solution tanx(tanx) 1 + secx(1 + secx) _________ + _________ = 2csc x 1 + secx(tanx) tanx(1 + secx) tan2 x 1 + 2secx + sec2x ________________ + _________________ 1 + secx(tanx) (tanx)1 + secx tan2x + 1 + 2secx + sec2x _________________________ 1 + cos 1/x(tanx) sec2x + 2cos 1/x + sec2x _________________________ 1 + cos 1/x(tanx) This is as far as I get before I get lost.
