Cheers for the help so far, and no I didn't mean e^-z.

Differentiating is the easy part, but finding the stationary point is a bitch.

Ok, back:



That's that graph for 0< x <2*pi.

For (iv) draw in -1/2*x and how many times the lines intersect = number of solutions (as far as i remember anyhow).
