I'm supposed to find a polynomial approximation centered at 0 for f(x)=cos(x) accurate within 0.005 for -0.1<x<0.4. I know I need to figure out what n should be to get the max error of 0.005, but I'm not sure what I should make the bounds of the integral to find the error (from n to infinity?) and I'm also not sure where the 0.1 and 0.4 fit in. Thank you!
