Let f(x) = cos(x) = ; then, consider the following rational approximation
called the Pade Approximation. Determine the coefficients of r in such a way that
f(x) - r(x) = γ8x8 + γ10x10 + ......
Please see the attached file for the fully formatted problems.
The Pade approximation is investigated. The solution is detailed and well presented. The response received a rating of "5/5" from the student who originally posted the question.
