(c) We can continue to add terms to our approximation. Find a formula for the
"cubic approximation" C(r) of a function g(x) around x = c. You should leave
your answer in terms of g and its derivatives.
(d) Repeat the previous two steps but for a cubic approximation using the formula
you found in the previous step. What is the approximate value of e0.1 using
your cubic approximation?
