METODI ANALITICI PER L'INGEGNERIA II

The aim of teaching is to provide theoretical skills and solving techniques in the field of calculus with the aim to apply them in physical or engineering courses. In particular, the target will be to develop skills about power and Fourier expansion of functions, differential calculus and integration of real functions of two or more real variables, solutions of ordinary differential equations and integration on curves or surfaces.

Frontal teaching with classroom exercises.
