Use forward and backward difference approximations of O(h) and a centered
difference approximation of O(h
2
) to estimate the first derivative of the
function below. Evaluate the derivative at x = 2 using a step size of h = 0.2.
Compare your results with the true value of the derivative. Interpret your
results on the basis of the remainder term of the Taylor series expansion.
all that typing, and no function.
How about you show your work, and how far you got?
