Learning outcomes

Students will acquire a mathematical knwledge of informative character using an ample basic instrumentation to describe different physical phenomena. In particular, at the end of the course, students will be able to: solve problems of conditioned extremals, compute simple integrals of functions in many variables; to compute simple integrals of functions defined on surfaces.

Teaching methods

Blackboard lectures

Assessment methods

Exercise and theory exam, both written, to be passed in the same exam session: first the exercise part, then the theory part. The exercises have to be solved explaining how the solution os found, justifying the steps. The student can take the theory exam if she/he has a grade not inferior to 18/30 in the exercise exam.
