SumConvergence
SumConvergence[f,n] gives conditions for the sum ∑+n%∞f to be convergent.
SumConvergence[f,{n1,n2,…}] gives conditions for the multiple sum ∑+n1%∞∑+n2%∞… f to be convergent.
SumConvergence[f,{n,a,∞}] gives conditions for the sum ∑+n=a%∞f to be convergent on the interval [a,∞).
SumConvergence[f,{n,a,∞},…,{m,b,∞}] gives conditions for the multiple sum ∑+n=a%∞…∑+m=b%∞f to be convergent.
