## Learning Outcomes

The basic problem of vector analysis is: How to differentiate and integrate vectors? This question raises in certain engineering applications of mathematics, especially when we consider a flow of given substance, no matter whether that substance is, say, water flowing in a pipeline, or energy carried by a radio wave. During this course a student will learn the basic concepts and theorems of vector analysis, and to apply them in the problems of mechanics, fluid mechanics, and electrical engineering. The student also learns to differentiate and integrate vectors in general curvelinear coordinates, and not only in the familiar xyz coordinates.

## Student's Workload

The total amount of student's work is 81 h, which contains 42 h of contact studies. The assessment of student’s own learning 1 h is included in contact lessons.
