I'm stuck on proving a couple trig identities. Ignore question 1, I got it now. 1. cos2x / 1 + sin2x = 1 - tanx / 1 + tanx 2. sin2x / 1 - cos2x = 2csc2x - tanx

That way, people won't waste their time answering questions that you've already figured out how to do in the meantime.
Alrights, sorry. I get frustrated but then later on I calm down and I can figure it out easier. I don't know, it's just me but I'll keep that in mind.
