This is a question about you grade 11 trig identities lesson on your website. I'm on quite understanding example 3f) question: 1/1-sinx - 1/1+sinx = 2tanx/cosx I've worked through the whole thing basically so I have: Left side: Right side: (1+sinx) - (1-sinx) =(2sinx/cos^2x) ----------------------------- cos^2x I'm confused as what to do from here; I'm not sure how the numerator for the left side turns into 2sinx. I've looked at the answers on the website but it shows that the (1-sinx) turns into a (1+sinx) and I'm not sure how.
