use integration by parts .disintegrate the terms into two parts : numerator=a and (1/denominator)=b.

so it will reduce into

$a b dx. then apply integration by parts.

thanks loote...My answer doesn't exactly match with the calculator but i did these using the table of intregals. I hope the answer only differs by a constant...

I'll try to do these without using the table, using by parts..let's see what happens.. i'll let u know
