Multivariable Calculus

Multivariable Calculus (MTH316)


MTH316 Multivariable Calculus will introduce students to the Calculus of functions of several variables. Students will be exposed to computational techniques in evaluating limits and partial derivatives, multiple integrals as well as evaluating line and surface integrals using Green’s theorem, Stokes’ theorem and Divergence theorem. Applications of Lagrange multipliers to optimization and applications of integration such as dynamics, electromagnetism and thermodynamics will also be emphasized.
