Hi

I would like to know what is ∫1/x^2-∫1/x^2 from 0 to 2.is it zero or undefined meaning that it is infinity ? (because each integral is undefined at zero).

That is undefined because the two separate integrals are undefined. The theorem that $\displaystyle \int f- g dx= \int f dx- \int g dx$ only holds if the two integrals on the right are defined which does not apply here.
