1) INT(from 0 to infinity) (cosx)/(x + e^x) dx

2) INT(from 0 to 1) [(x-x^2)^1/2]/x dx

Thanks, two bugged me, so I left them out and almost forgot about them completely. I think the 2nd is trivial.. but my brain needs sleep!

Ta!

I see the first one straight away, thanks. I was too caught up struggling to compare it with something like 1/x^2.

Will try the second now.
