## Learning Outcomes

A good mathematical knowledge is a basic requirement for engineering studies. Without a basic knowledge of mathematics is impossible to carry out the daily tasks of an engineer, and understand the professional literature. This course begins from the very basics of mathematics, and in principle it does not assume any previous knowledge in mathematics. At the beginning the student is made familiar with the natural numbers and their basic arithmetic operations. Little by little, the student is introduced to basic algebra, and to an important concept of function. The most common functions and their properties are presented to the student. An important role in the course is played by the art of solving equations, as well as systems of equations. The student is also made familiar with the basic trigonometry and -geometry.

81 h, which includes 42 h of scheduled contact studies.
The assessment of student’s own learning 1 h is included in contact lessons.
