The Course: The analysis necessary to introduce the support needed for the “study of change” and then this actual study. The Calculus, as described by Louis Leithold, is the study of rates of change of quantities and their relationships. The applications are numerous. Because of the nature of mathematics ( the need to reverse any operation or idea), further studies allow area of general plane figures, length of general curves, and volume of general solids to be calculated. Technology and newer methods allow a decent introduction to differential equations.
