We've just started Methods in Calculus in Further Maths but are yet to start it in Maths. I'm just wondering what method of Integration is used to get this integral:

It's just seeing what happens when the upper limit goes to infinity.

Below the red line, they've integrated it?

Then consider the upper limit going to infinity. Does it converge/is it finite.

Yes, that's the indefinite integral.

Sorry my fault, I don't think I've been clear, how would I integrate that? 1 / x^a when x != 1

1/x^a = x^-a. You should know how to integrate x to a power (other than x^-1).

I'm a donkey! Sorry had to learn 3 weeks of integration in one lesson. My brains a little fried..
