Hi,

I am stuck with the trig equation $\displaystyle cot^2x = cosecx$, range 0 to 360

The answer should be 38.2, 141.9.

I know that $\displaystyle cot = 1/tan$ and $\displaystyle cosec = 1/cos,$ but keep having problems after this.

Is there any general advice for solving these type of equations, particularly involving cot, sec and cosec. I keep getting stuck with the fractioned form of the equation ie $\displaystyle 1/sin$.

Any help would be much appreciated,

Thanks

Dominic
