Hi :)

I forgot how to solve sigma problems and these are one of the last problems I need to solve for my AP Calc summer assignment. If someone could help, I would greatly appreciate it:)

The directions say to expand and simplify:

a)

4

E n2 / 2

n=0

b)

1

E1/n^3

n=1

I am pretty sure you start off with substituting (n=..) for n but how would I continue the problem?

Thanks for helping!(Hi)(Happy)
