Mathematical Analysis IV B

Objectives

The program deals with the study of ordinary differential equations. We hope that the students be able to determine the general solution and particular solutions of various types of ordinary differential equations.  

We intend the students use the Laplace Transforms for solving differential equations and corresponding initial value problems.

In the last part of the program we intend to familiarize the students with Fourier Analysis in such a way they could be able to use it as a tool in solving the most important partial differential equations occuring in engineering.

Teaching method

General (3hs/week) and exercises (2hs/week) class. Homework and examples will be solved in exercises class.

Evaluation method

The evaluations consists in three tests. If the grade othe third test is equal or superior to seven, then the final classification is the unweighted average of the three tests, rounded to the near integer (n.5 is rounded to n+1).

Students with average equal or superior to 9.5 but who fails to satisfy the minimum of 7.0 in the third test, will have "avaliação contínua" equals to 9.

For students that fail in the evaluation, there is a final exam.
