Course Outline
 Review: linear algebra and functions of several variables
 Differentiation of functions
 Multivariate Chain Rule
 Quadratic forms, Hessian matrices, and extrema of multivariate functions
 Constrained optimization and Lagrange multipliers
 Approximation by polynomials
 Integration of functions
 Change of Coordinates: spherical and polar coordinates
Students will develop familiarity with: “partial derivatives, gradients, tangent planes, the Jacobian matrix and chain rule, Taylor series, extremal problems, extremal problems with constraints and Lagrange multipliers, multiple integrals, spherical and cylindrical coordinates, law of transformation of variables.”
Prerequisites: This course requires Linear Algebra (MATA22H3 or MATA23H3 or MAT223H) and Calculus (MATA36H3 or MATA37H3 or MAT137Y or MAT157Y). This course will be very difficult if you do not have the prerequisites. If you want to attempt the course without these courses, please contact Parker immediately.
Note that this course excludes: MAT232H, MAT235Y, MAT237Y, and MAT257Y.
