    you're asking if the integral is convergent or divergent?

    if \[\int_0^{\pi}\frac{d\theta}{\sqrt{\pi-\theta}}\] is convergent, you can conclude that the integral in question is also convergent.

    How do I know that integral you stated above is convergent? That's the part that is troubling me.

    why don't you evaluate the definite integral? if it is a value, then the integral is convergent.

    Oh okay, I thought it was improper. I just realized that it was definite. Thanks!

    it is an improper integral, but after integration, the function is continuous in that interval, so you can treat it like an ordinary definite integral.
