I think I got it now. For number 2, I separated the two fractions from the left side of the initial equation and got this:
(sinx)/(1) - (sinx)/(cosx) + (sinx)/(1) +(sinx)/(cosx) = then I combined similar terms and got this:
(sinx)/(1) + (sinx)/(1) = now I flipped the fractions and got this...
Hmmm I kinda see what you're saying. I started all over with the first one and this is what I got, can anyone check if I did it correctly? It proves to be correct, at least to me.
1 + (1/cos^(2)x)(sin^(2))x) = I then multiplied the two fractions, giving me:
1 + (sin^(2)x)/(cos^(2)x) = now...
Proving identities is a pain! Thanks in advance, guys!
Homework Statement
