# MTH220 Ordinary Differential Equations (8)

This subject is designed to get students acquainted with the basic methods of solving ordinary differential equations. The methods considered include exact integration, Laplace transforms and power series. The following types of equations are considered in detail: separable, Bernoulli, homogeneous, first order linear and higher order linear with constant coefficients. An important role of ordinary differential equations in applications is illustrated by examples of electric circuits and phenomena that involve various types of growth (eg exponential, logistic).
