# Mathematical Analysis II D

## Objectives

At the end of this course students are expected to:

- have knowledge of the concepts, notations and objectives of Mathematical Analysis in R ^ n, especially for n = 2 and n = 3;

- are able to solve practical problems using derivatives and integrals of functions of several variables.

- have knowledge of the main theorems of differential and integral calculus, especially the theorems of Green, Stokes and divergence.

- know the notion of numerical series and know how to analyze the convergence of series of nonnegative real numbers and alternating series

### Prerequisites

The students should have knowledge of mathematical analysis of functions of one variable corresponding to the completion of the course of Mathematical Analysis I. Should have knowledge of linear algebra and analytic geometry, in particular of vector calculus in R ^ 2 and R ^ 3, the equations of lines and planes in R ^ 3, the matrix representation of linear functions defined on R ^ n with values on R ^ m and matrix calculation.

### Teaching method

The professor gives the course by lectures, where he explains all topics referred to in the syllabus. Problem sheets are provided to students to be worked outside the classroom with prior knowledge acquired during the course. Practical classes are taught, where the teacher clarifies the doubts about the problems given previously and the more relevant problems are solved in the blackboard.

Students still have the so-called "horário de dúvidas" where they can clarify their doubts with the teacher

### Evaluation method

Continuous evaluation.

In order to be eligible for continuous evaluation, the student may attend 2/3 of pratical sessions or 2/3 of theoretical sessions. The continuous evaluation method is based upon two tests. The student is aproved if the grade average is greater  or equal to 9.5. In the final exam date, the student may optionally improve one of the tests. If an approved student desires to improve the grade by exam he   must express his intention to the responsible teacher so that the aproval grade is previously registered.

Exam evaluation

Any student inscribed in the discpline may attend to the exam, being aaproved if the final grade is greater or equal than 9.5.

If necessary, the responsible teacher  may individually require an extraordinary evaluation.
