### Mathematics 2

#### Course Description

#### General Competencies

Student is supposed to achieve a good level of understanding of theoretic concepts and principles in the topics of series, power series, Taylor series, analytic geometry in space and differential calculus of several real variables. Student will be able to select and apply corresponding methods and techniques of calculations from topics mentioned above. Student will synthesize all above competences and use it in the solving of ordinary differential equations(ODE's). Student will be able to design the differential equation, as a mathematical model, related to simple examples of the engineering practice.
