Find the limit as x goes to 1 of tan(pi*x/2)lnx

2. Relevant equations

using l'hopitals, lim f'(x)/g'(x)=answer

3. The attempt at a solution

i tried integrating by making the tangent part squared so i can divide by the tangent part, but i keep getting stuck. i think the answer is either 1 or infinity.

help please? thanks
