1. Organization: The unit is offered in two concurrent modules. Module 1 is concerned with topics in advanced calculus and vector analysis and Module 2 with ordinary and partial differential equations. 2. Content: Module 1 - deals with smooth scalar and vector functions of scalar or vector variables; in particular with curves and surfaces in space and scalar and vector fields. Line, surface and volume integrals and the theorems of Gauss and Stokes lead to the development of the fundamental equations of mathematical physics and the discussion of conservative fields and potentials. Module 2 - deals with the description of linear systems through linear differential equations. Laplace transform techniques are developed to analyse the nature of system response to impulses and other inputs. Fourier series and transform techniques are also discussed.
