Learning objectives

Knowledge and understanding:
basic theory of vector spaces and geometry of space.

Applying knowledge and understanding:
a) solve systems of linear equations;
b) diagonalize (symmetric) matrices;
c) solve easy problems of analytic geometry;
d) recognize the type of a conic and write its canonical form.

Making judgements: basic.

Communication and learning skills:
properly express themselves with mathematical language.


Precourse of Mathematics
