CALCULUS IN ONE VARIABLE | FMA415 |

**Aim**

The course aims at giving a basic treatment of one-dimensional calculus. Particular emphasis is on the role this plays in applications in different areas of technology, in order to give the future engineer a good foundation for further studies in mathematics as well as in other subjects. The aim as also to develop the students' ability in problem solving and in assimilating mathematical text and communicating mathematics.

*Knowledge and understanding*

For a passing grade the student must

be able to set up and solve some types of linear and separable differential equations that are important in the applications.

be familiar with the logical structure of mathematics, in the way it appears e.g. in plane geometry.

be able to give a general account of and illustrate the meaning of mathematical concepts in calculus in one variable that are used to construct and study mathematical models in the applications.

be able to account for the contents of definitions, theorems and proofs.

*Skills and abilities*

For a passing grade the student must

in the context of problem solving be able to show capability independently to choose and use mathematical concepts and methods in one-dimensional analysis, and to construct and analyse simple mathematical models.

in the context of problem solving be able to integrate knowledge from different parts of the course.

be able to show capability to explain mathematical reasoning in a structured and logically clear way.
