Students will acquire knowledge about ordinary differential equations, learn how to solve selected types of equations, with a point to linear equations. The students will be able to use the acquired knowledge at posing and resolving problems that appears in practices, such as, mechanics, environment sciences, and economics.

Knowledge and understanding:
Knowledge and understanding of the basic concepts of transferring non mathematical problems to a corresponding mathematical models.
Application:
Differential equations are one of the basic subjects necessary to understand mechanics and other subjects of natural, technical and social sciences. Knowledge is necessary in modelling of almost all systems.
Reflection:
Integrating theory and practical applications in solving problems.
Transferable skills:
Posing a problem, selection of a method and its application in solving the problem. Analysis of the results from the cases. Skills in using literature. Knowledge is transmitted to virtually all sciences.
