I offer courses in mathematics (geometry, arithmetic, algebra), but also for university students (linear algebra, vector calculus, differential equations). The course includes theory, practical exercises and simulations using calculation software such as Scilab to illustrate the results. I also offer courses in Physics (Classical and Electromagnetism). Practical examples oriented towards engineering applications. I offer courses in electronics (circuit theory, analogue and digital electronics and telecommunications) and computing (programming, Linux). Finally, I offer courses in Spanish. I use everyday situations and current conversation topics to improve your level.
