Matrices and matrix algebra are introduced in order to solve systems of linear equations by Gaussian elimination. Differentiation is generalized from functions of one variable to functions of several variables, through the concept of partial differentiation. A study of systems describable by linear differential equations is begun by looking at some simple examples of engineering interest. The solution of ordinary differential equations using the methods of complementary function and particular integral.
The course is only available to students on the Graduate Apprenticeship in BEng in Civil Engineering.
