This course unit provides students with a framework for applying advanced concepts and techniques learned throughout its course, with an emphasis on differential and integral vector calculus, while granting him a background on the field of electromagnetism. This background will enable the student to better understand the world, its constituent parts and interactions between them.

E-learning

Continuous assessment is privileged: 2 digital written documents (e-folios) during the semester (40%) and a final digital test, Global e-folio (e-folio G) at the end of the semester (60%). In due time, students can alternatively choose to perform one final exam (100%).

Course unit pre-requisites:
• knowledge of vector, differential and integral vector calculus and linear algebra.
