1. When I get solutions like cot(x)=2 I just use 1/tan(x)=2/1 and flip them both, but I don't know what to do when it's something like cosec(x)=0, should I just realise that cosec(x) can never =0 because of the graph? And in that case when I get cot(x)=0, should I just do cos(x)/sin(x)=0?
2. If you got cot(x)=0 then what you suggest does work. Hence x=90. This is quite interesting actually. Never thought of doing that before.

has no solutions, like you said.

occurs precisely when .
