Optimization Problems in Calculus

The video tutorial introduces optimization, a concept related to finding maximum and minimum values of functions, and its connection to curve sketching. It reviews parabolas and the method of completing the square, then explains how calculus can simplify finding extrema by using derivatives. The tutorial focuses on solving an open top box problem, deriving a volume formula, and using calculus to find the maximum volume. The session concludes with a summary of the optimization process.
