# Mathematical Analysis II E

## Objectives

Domain of the basic techniques required for the solution of ordinary differential equations as well as to the Mathematical Analysis of functions of real variable.

The students should acquire not only calculus capabilities, fundamental to the acquisition of some of the knowledge lectured in other Engineering subjects, but also to develop methods of solid logic reasoning and analysis.

These capabilities ensure autonomy in the analysis and in resolution of new problems to the future engineer, opening the possibility to acquire more complex mathematical tools, possibly needed through is career.

### Teaching method

Theoretical classes consist in a theoretical exposition illustrated by application examples.

Practical classes consist in the resolution of application exercises for the methods and results presented in the theoretical classes.

Any questions or doubts will be addressed during the classes, during the weekly sessions specially programmed to attend students or in individual sessions previously scheduled between professors and students.
