Question 1114560: how to establish this trigonometry identity function
1-cosx/1+cosx = (cscx-cotx)^2
I tried to do it by using (a-b)^2 , but i got stuck in meddle of the works
Can someone give me some tips about this trig id function ? Thank You

It would help us to help you if you showed us your work -- instead of simply saying your tried it and it didn't work.

This one works out very nicely if you use (a-b)^2 to expand the right hand side.

Then use the most common trig identity (which you will use 10 times as often as all the others together) to get the expression in terms of cosx only:
