We arrived at Formula 6.3.2, / by using cylindrical shells, but now we can use integration by parts to prove it using the slicing method of Section 6.2, at least
for the case where f is one to one and therefore has an inverse function t. Use the figure to show that
Make the substitution y = f(x) and then use integration by parts on the resulting integral to prove that
