Calculate the integrals if they converge.

10.) Integral from 1 to infinity of
X/4+X^2 dx

14.) integral from Pi/2 to Pi/4 of
Sin X / sqrt cos x dx

22.) integral from 0 to 1 of
ln x/x dx

I'm having problems with working these out to figure out if they converge or not. Any help or tips would be appreciated
