How would you determine the degree of the Maclaurin polynomial required for the error in the approximation to be less than 0.0001 for

f(x)=cos(pi*x^2) approximating f(0.6)? Thanks!

And it looks to me as though the required degree is 16.

Look at the post on Taylor polynomials just below this one for more details.
