Why Do We Need the Derivative for the Surface Area?
Hristova, Yulia; Zeytuncu, Yunus E.
PRIMUS, v26 n5 p393-405 2016
Surface area and volume computations are the most common applications of integration in calculus books. When computing the surface area of a solid of revolution, students are usually told to use the frustum method instead of the disc method; however, a rigorous explanation is rarely provided. In this note, we provide one by using geometric observations and the Squeeze Theorem.
