MAT 230 is the third and final course in the sequence of calculus courses. In the first year of their calculus studies, students learn concepts of differentiation and integration for functions with a single independent variable. MAT 230 is a course cover ing calculus computations involving 2 or more variables at the same time, a topic commonly called multivariable calculus. An intuitive and manipulative working knowledge of multivariable calculus is indispensable for electrostatics, fluid dynamics, solid mechanics, and many other fields of science and engineering that involve both space and time.
