Thanks for the help guys I appreciate it.
Now I have another problem though, ha, for the true derivative I'm getting another error now. Dont know if I entered the wrong derivative or what I did?
This is what I got:
% The true derivative
dyt = -exp(-x)*sin(3x) + 3exp(-x)*cos(3*x)...
The problem is: Compare the performance of the forward, backward, and central difference methods for estimating the derivative of the following function: y(x)=e^-xsin(3x). Use 101 points from x = 0 to x = 4. Use a random additive error of +/- 0.01.
I understand the process of solving this...
