Consider

(a) For what values of does the series converge?

(b) On what intervals of the form does the series converge uniformly?

(c) On what intervals of the form does the series fail to converge uniformly?

(d) Is continuous at all points where the series converges?

I would appreciate any help. Meanwhile I am trying to do the question by myself and would let everyone know of any breakthroughs.

Thanks
