Description for 2025/26

Many real-world problems are governed by differential equations, the solution of which can help us understand their properties. For instance, oscillation of a pendulum, and the population evolution of a fish species, can all be described by ordinary differential equations. This module, being a prerequisite for several modules in the second and third years, will introduce you to the basic techniques for solving differential equations and familiarize you with multivariable calculus, including partial derivatives, double integrals, and their applications.

Aims
The aim of this module is to introduce students to the solution of ordinary differential equations, and to Taylor series, elements of multi-variable calculus, including partial differentiation, double integration, and some of their applications.

Intended Learning Outcomes

recognize the type of ordinary differential equations (linear or nonlinear, constant or variable coefficients, order): 4
classify and solve several types of first-order ordinary differential equations (variable separable, linear and others which may be reduced to these): 1,4
solve first- and second-order, homogeneous linear ordinary differential equations with constant coefficients, as well as corresponding inhomogeneous ordinary differential equations with the right hand side of special form by the method of undetermined coefficients: 2,4
study number and power series for convergence; expand a function of one variable as Taylor series: 2,4
calculate partial derivatives, and find local maxima/minima, and restricted maxima/minima using the method of Lagrange multipliers, apply chain rule to multi-variable functions: 2,4
calculate double integrals and use them to find areas and volumes; change of variables under double integral, including polar coordinates: 3,4
