Fp integration ends up with something I've never seen

I'm doing question 3 page 93 of the aqa fp3 booklet. I've managed part a i) but cannot do part ii).

Ive looked at the answer and I know from just looking that I wouldn't have a clue. I've also tried an online integrator but it seems to hang up. I have noticed that the blue formula booklet has something in the differentiation section that looks a bit close but I've still not cracked it.

Are these types on integration typical of FP3 and if so can anyone recommend and practice resources.

No idea why they are upside down I'll try again

I think your mistake is this: 1x21x2=11x2\frac{\sqrt{1-x^{2}}}{1-x^{2}}=\frac{1}{\sqrt{1-x^{2}}}

You are so right. What a silly thing to do.

Next question. That integration is in the blue formula book. Thanks so much.
