How to determine whether the following series converges uniformly (and pointwise)

240 Views Asked by At

I want to know what the steps are to determine whether the following series converge 1) pointwise and 2) uniformly. And how to show if it converges(or doesn't). $\sum \frac{1}{x^k+1}$ on the interval (1,infinity) I've tried on myself for hours but couldn't find a way (tried M-weierstrass but that didn't work out well)
