Mathematics 2 (FSI-Z2M)

Students will be able to determine parameters needed in mathematical models of some real problems. They will acquire skills for analytical solution of some ordinary differential equations and their systems.

• Knowledge of the fundamentals of selected mathematical theories, which are needed in mathematical modelling in physics, mechanics, and other technical disciplines.
• The ability to think logically and systematically, to move from simpler to more complex and to express and argue accurately when solving problems.
• The ability to apply a suitable mathematical apparatus in solving some basic tasks appearing in mathematical models of real problems.

Knowledge of linear algebra, differential and integral calculus of functions of one variable.

The course provides an introduction to the differential and integral calculus of functions of more variables. It is also devoted to the fundamentals of the theory of ordinary differential equations and their systems. The main attention is paid to the use of the mathematical apparatus in solving some basic tasks in mathematical models of real problems. The course is the basis for successful completion of subsequent professional technical courses (machine design, technical mechanics, etc.).
