Homework Statement
Approximate the sum of the series S = [tex]\sum[/tex](n from 1 to Infinity) [tex]\frac{[(-1)^(n+1)]}{n!}[/tex] by calculating S_10.
Estimate the level of error involved in this problem.
AND
S = [tex]\sum[/tex](n from 1 to Infinity) [tex]\frac{[(-1)^(n+1)]}{n^4}[/tex]
Approximate the sum of the series by using the 20th partial sum.
Estimate the error involved in this approximation.
Homework Equations
None.
The Attempt at a Solution
Manually found the sum of the series using a GDC.
Error is less than [tex]u_{n+1}[/tex]. So I found [tex]u_{n+1}[/tex], but that gives the wrong answer for both the cases.
