Homework Equations
[tex]\cos(x)=\sum_{k=0}^{n}\frac{(-1)^kx^{2k}}{(2k)!}[/tex]
Pn- Taylor expansion of order n
The Attempt at a Solution
I know that in this case, in order to get an error less than 1/100, I need 18 terms/order 18(according to Wolfram Alpha). But does it mean that if I take the integral of cos(x) so I can take the integral of Pn and solve part (a)?
I am not really sure regarding part (b). Am I supposed to compute the integral of Pn that I (hopefully) found in part (a) and express it in sigma notation?
Thank you,
Thomas
