First attatchment is an integral I have been given.

Using different values of k I have to find out what value the integral converges too.

What I want to know is does this mean integrating the volume of circle with radius 1.

Shown in formula in the second attachment, I have also arranged it using polar coordinates.

And if that is right, I have found but only using mathcad that if k = 1/infinity the value converges to pi.

Is that right, because how I suppose to integrate the function shown using fractions to k, surely this is too complex to do by hand.

Cheers Ash
