    Multiple Integral

    For the double integral shown below, investigate values of k that make the integral converge.

    \int\int_{(x^2)+(y^2)<=1} \frac{dA} {(x^2+y^2)^k}

    To what value does it converge?

    Switch to polar coords

    \int_0^{2 \pi} \int_0^1 r^{1-k} dr d \theta = 2\pi \int_0^1 r^{1-k} dr and determine the k values that there's an answer.
