## Learning Outcomes

During the Advanced Analysis course the student will deepen the knowledge gained during the courses of Differential calculus and Analysis. The largest individual part of the course consists of complex analysis. In that part of the course the student will learn to differentiate and integrate functions of a complex variable. Complex analysis is largely based on power series, and therefore, as a preparation for the complex analysis, the student is first familiarized with the power series of functions of a real variable, their divergence and convergence. Complex analysis, in the level considered in this course, is intented to provide the student the necessary knowledge for the Integral Transforms course. Power series may also be used for the solution of differential equations.

The student is also made familiar with basic partial differential equations and their solution by means of the separation of variables. The course end with a brief review on the calculus of variations, which may be viewed as a one step forward from the usual differential- and integral calculus. Among other things, classical mechanics as a whole may be derived from a single principle formulated by means of the calculus of variations.
