The number of real solutions to is?
-- ok, so i figured that cosec^2(x) = 1 + cot^2(x), so that brings it to
if i am right?
so how many solutions are there then? 4?
EDIT: using a graphics calc, i graphed x^4 - x^3 -1 =0 and checked how many x intercepts there were, and so there were 2 real solutions.
But is there a way of doing this without the calculator?
