I will be honest this is my first post here and am 100% new to the site. But I have been staring at this problem for nearly an hour and I am stuck. I am trying to verify the following identity.
(sin^2(t))/(1-cos(t))= 1+cost. and this is what I have so far.
I assume I should pick apart the left side as its more complicated. so (sin^2(t))/(1-cos(t)) --> (1-cos2t)/2)/(1-cost). I think but from there I am stuck. Am I even looking at things from the right direction? Any suggestions would be appreciated.
