The two problems require to approximate the series to four decimal points. both are assumed to be convergent
1) sin2n/n5 from 1 to inifinity
I have no idea what to do because Its not an alternating series and therefore I cant use the alternating series est thm and I dont have advanced enough learning to know how to take the integral for the intergral approx test.
2)(-1)n-1(n)/(n4+1) from 1 to infinity
