(Text)
The book offers a practice-oriented introduction to the mathematical methods of electrical engineering. The focus is on the solution of ordinary and partial differential equations using analytical and numerical methods. The analytical methods are opposed to the numerical methods. The differential equations were chosen with a view to the problems of electrical engineering. It is shown how they can also be transferred to mechanics or thermodynamics. Numerous examples and exercises with elaborated solutions facilitate the transfer of knowledge to applications.
