Taylor series approximation problem

7 views (last 30 days)
we are considering a Taylor series approximation of f(x) = e^(-x)
my questions is how to compute the Taylor Series approximation of f(x).
The requirements are: the code should take as input x_i, x_i+1, and the order, n.
The code should output the normalized true error e_T, at x_i+1
I'm totally lost where to start, hope to get some hints or help!

As an example,
syms x
T = 
fn = function_handle with value:
ans = 0.0216
You can of course find more examples in the documentation for taylor() and matlabuUnction()

Sorry Matt for the late reply, I think what works, but I finally wrote a whole for loop to run that! Thanks for helping!
