solve this integral for p

[Dell]

for which values of p does the integral converge

0\intpi/2(tan(x))pdx

i know there is a rule that a\int∞1/xαdx
if
α>1 does converge
α<1 does not converge

so can i apply the same logic here saying
0\intpi/21/(tan(x))-pdx
so if

-p>1 does converge
-p<1 does not converge

or is this not good since i have d(x) and not d(tan(x))??

do i need to say tanx=t dt=dx/cos2x
if so how do i continue from here since ill have

\inttp/cos2x dt

the books answer is 1<p<2
can you please show me how
