Group Title
Can a realvalued function f(x, k) which has domain x: Reals and k: Positive integers and 0 have the following property?\[\lim_{n\rightarrow\infty}\sum_{k=0}^n\int f(x,k)dx\]The above converges for some x while the below diverges\[\lim_{n\rightarrow\infty}\sum_{k=0}^nf(x,k)\]for the same x?

I appreciate your try to help but I did pass calculus and if it could have been solved that easily then I wouldn't have asked.

Interesting. So we get: \[\sum_{k=0}^\infty\frac{x^{k^2+1}}{k^2+1}\] Which does indeed converge for x = 1 by pseries and direct comparison test.
