Gosh - what a great tip. I didn't know the integrator existed. Thank you. Having got the answer from Wolfram I'm kind of pleased that I hadn't missed an obvious solution. Thank you all.

Yes it is - the root of (1+kcos(x))

Ah! So absorbed by it, I've missed the most important bit! I'm trying to integrate it to get the area under the curve between x=0 and x=pi

I am rediscovering my long lost "A" level maths and have been having lots of fun working on puzzles. Unfortunately, I seem to have hit something of a wall in the following simple expression that is repelling every attack I launch: f(x)=Sqrt(1+kcos(x)) I have tried substituting x=arccos(w)...
