Another trig identity: cosec^2 2x - cot 2x = 1Watch
Stuck with the above. Needs to be solved in the range 0 < x < 180.
Just need to force it into a quadratic form... here are my attempts. Any ideas as to where I'm missing the plot?
and 1/tan 2x = 0. or 1/tan 2x = 1
Thus, we can solve tan 2x = 1 in the range 0<x<180. The 1/tan 2x = 0 can be ignored as infinity is given when reciprocated?

Not too hard?
