MTH218 Multivariable Calculus (8)

This subject extends the study of calculus to functions of several variables. Partial derivatives are reviewed and double and triple integrals introduced. The subject also covers vector calculus, which includes differential operators (gradient, divergence and curl) and line and surface integrals. Vector calculus culminates in higher dimensional versions of the Fundamental Theorem of Calculus: Green's Theorem, Stokes' Theorem and the Divergence Theorem.
