MATHEMATICAL ANALYSIS AB
Learning outcomes of the course unit
The course provides the basic notion of calculus.
Students are supposed to be familiar with the basic mathematical tools taught in High School: basic set theory, elementary algebra, logarithms and exponential, trigonometry, equations and inequalities, basic plane analythical geometry.
