This module applies advanced calculus to practical, computational and mathematical problems. It covers the approximation of a general function by polynomials, the defining equations of lines and planes, the method to find maximum or minimum of a function, as well as the calculation of area, volume, surface area, mass, centre of gravity. The course is for students with advanced calculus background and with interest in the applications of calculus. Major topics: Sequences. Monotone convergence theorem. Series. Absolute and conditional convergence. Tests of convergence. Power series and interval of convergence. Taylor's series. Differentiation and integration of power series. Vector algebra in R2 and R3.
