Aim of the course -
Last update: JANCARIK/PEDF.CUNI.CZ (27.05.2010)

Primary purpose of the course is to make students acquainted with basic ideas, knowledges and connections of infinitesimal calculus of two or more variables functions in relation with similar courses on one variable functions. Secondary aim is to prove, repetite and fix knowledges of previous courses especially from mathematical analysis, but from geometry (curves, surfaces) or algebra (vector space, linear, quadratic forms) as well.

Teaching methods -
Last update: JANCARIK/PEDF.CUNI.CZ (27.05.2010)

Lecture and seminar.

Requirements to the exam -
Last update: MOSNAF/PEDF.CUNI.CZ (18.11.2011)

- credit requirements: active participation at seminars, one control test, which demonstrates the ability to manipulate and use appropriate concepts, knowledge and relationship by the examples (two examples on differential calculus, one example on integral calculus), (there will be two terms during the examination period for possible correction)
- exam requirements: understanding of given concepts, relationships in three questions (the first question examines certain concept, its definition, introduction..., second question relates to some process, method, inference, problem solving, the third question asks the student to decide on validity of submitted state and justify his decision or support it by a counterexample)
