Hi, just needa clear up how to do some certain questions before i start uni in a few weeks.
Intergrate: sin(x) . cos^4 (x)
I'm not sure if i needa split up the coses to use an identity or whatever.
intergrate: xe^(x^2+1)
= xe(x^2+1)/2x
(1/2)e(x^2+1) ?
I think that is right but not certain.
and
Intergrate: 5/m - 3√m expressing answer in surd form
I get as far as 5ln|m| .. then get slightly confused by the second part.
Cheers in advance to thoose who can help and shows steps to refresh me.
