My friend sent me some Trigonometric proving identity questions to practise and i am usually good at them but i havent done them for a while so i have gotten a bit rusty plus these ones to me are very difficult so i would like some assistance.(adsbygoogle = window.adsbygoogle || []).push({});

Prove 1/1+sin + 1/1-sinx = 2secsquaredx.

ok so left side looks hardest so i started with that and did it first. It may look confusing writing the divisions.

1/1+sinx + 1/1-sinx

1/1+ cosx/cotx + 1/cosx

cotx+1/cosx + 1/cosx

cotx+1/cosx + 1

cscx/cosx +1

Ok so that is where i have gotten to and it doesnt seem like i can get it to equal the right side. I think i have screwed up a step and i would like any assistance if possible. Please help
