I'm taking a class and have been assigned a problem from our text. I have no problem working it with a pen and paper. I have a big problem working it in MatLab. The problem statement is use zero through third order Taylor series expansion to predict f(3) for f(x)= 25*x^3-6*x^2+7x-88 using a base point at x=1. Compute the true percent relative error for each approximation. The code I have so far does the Taylor expansion fine but I am unable to plug the value of three into the returned equations. How can I do this? My code is
function [g] = ans(y) x=3 trueval=25*x^3-6*x^2+7*x-88 syms xf=25*x^3-6*x^2+7*x-88 for n=(0:4) y=taylor(f,n,1) end Any help would be greatly appreciated. Thanks
