Learning objectives

Knowledge and understanding.
Students must achive thorough conceptual understanding of the theoretical foundations of multivariable differential and integral calculus as well as computational fluency.

Applying knowledge and understanding.
Students must be able to apply the forementioned notions to solve medium level problems related to the field of study and to understand how the forementioned notions can be used for solving problems in a more applied context.

Making judgements.
Students must be able to evaluate coherence and correctness of results obtained by themselves or by others.

Communication skills.
Students must be able to communicate in a clear, precise and complete way mathematical statements in the field of study, also in a broader context than mere calculus.

Prerequisites

Differential and integral calculus for functions of one real variable. Linear algebra.
