reverse the dx/dy you get and you will get an equation which will be 1/((1/2)cosy), now cos y is the same as squareroot of (cosy)^2, write (cosy)^2 in terms of (siny)^2 and rearranger from first euation to write in terms of x. Hope that makes sense

I have an idea although I don't quite understand how you end up with 8 outside the brackets.

Thanks in advance.
