Learning objectives

Knowledge and understanding.
Students must demonstrate knowledge and understanding of the basic results of multivariable calculus and ordinary differential equations. The course emphasizes concrete computations over more theoretical considerations with little emphasis on exceptional cases.

Applying knowledge.
Students must exhbit thorough conceptual understanding and computational fluency in standard cases.

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 and precise way mathematical statements in the field of study, also in a context broader than mere calculus.


Solid knowledge of single-variable calculus and linear algebra.

Course unit content

Multivariable calculus and ordinary differential equations.

Full programme
