MIT OCW - 18.03 Differential Equations (Spring 2003)

MIT OCW - 18.03 Differential Equations (Spring 2003). This consists of 33 video lectures given by Professor Arthur Mattuck, studying Ordinary Differential Equations (ODEs), including modeling physical systems. Ordinary differential equations (ODEs) deal with functions of one variable, which can often be thought of as time. The topics covered in this course include: Solution of first-order ODEs by analytical, graphical and numerical methods; Linear ODEs; Undetermined coefficients and variation of parameters; Sinusoidal and exponential signals; Complex numbers and exponentials; Fourier series, periodic solutions; Delta functions, convolution, and Laplace transform methods; Matrix and first order linear systems; and Non-linear autonomous systems.
