Course objectives
This course focuses on several branches of applied mathematics. The student is exposed to complex variable theory and a study of the Fourier and Z transforms, topics of current importance in signal processing. The course concludes with studies of the wave and diffusion equations in cartesian, cylindrical and polar coordinates.
