Answer 5

their are no limits

Answer 6

Blimey i was hoping for something easier haha. Ok so i think its by substitution?

Answer 7

lol its very difficult, umm you could do u substitution you could also try trig substation i was actually just seeing what level people on this site could do. It's a university integration question btw

Answer 8

i think you can use u.
let u = x^2, therefore x = root u
du/dx = (using decimals for easier reading) 0.5u^-0.5

Answer 9

Had i refreshed my memory on a level integration i'd be more useful :(

Answer 10

shah its okay ill ask my prof :) thnkx though

Answer 11

I have a feeling that a trig substitution is was youre meant to do though :/

Answer 12
