DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
Problem-solving with recourse to traditional analytical methods has a reduced expression, particularly when the problems are of a practical nature, generated by applications within the engineering. The analytical study is however not neglected and MIEC studies program includes disciplines of mathematical analysis and algebra where students acquire the knowledge on what all subsequent application techniques will rely. On the area of applied mathematics, numerical methods allow an important extension of kinds of problem-solving techniques, intervene in situations where the analytically is impracticable or where the nature of the problems, the data with which you work or the type of solutions in vista, require numerical approaches. The numerical analysis thus extends the possibilities of math in solving engineering problems.
Concepts and techniques are presented according to Analysis and Algebra knowledge and, whenever possible, the theoretical exposition is supported by practical examples and graphic representations. Theoretical aspects are presented with enough detail to exhibit the applicability of formulas. Additionally, methods are analyzed and compared in what concerns their efficiency, accuracy and applicability. Students are encouraged to develop algorithms for the numerical methods. In practical classes, several case studies are solved on the computer using Matlab. This curricular unit is inserted in the Moodle platform, in order to enhance the discussion among all participants. In this platform, all students have access to every issue provided by the teachers and may strengthen their concepts by solving self-evaluation tests whose results are immediately commented. They may also use the forums to bring questions before all the community of Numerical Analysis.
DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
The theoretical issues are accurately presented in lectures and the use of computers help to achieve the objectives of the curricular unit, related to the use of different numerical techniques for solving engineering problems. It allows to provide working tools for subsequent curricular that use computation intensively. The use of Moodle also allows better interaction between all participants of the curricular unit and consolidates the concepts by doing self-assessment tests.

Achieving final classification requires compliance with attendance at the course unit, according to the L.EC assessment rules. In regular classes, attendance will be registered.
Distributed assessment is optional.
1. Calculation formula of final grade for grades greater than or equal to 7.5 in the Final Exam (EF). Final mark (CF) is calculated according to:
CF = maximum {EX; AD} where,
EX – Final Exam Mark, in situ
AD = 30% x MP + 70% x EX
MP is the classification of the distributed evaluation component, obtained by activities:
- Mark of positive participation in 3 Moodle activities (10%)
- Summative test mark (20%)
2. For exam grades lower than 7.5 the final mark is the exam mark.
To achieve a classification of 18 or above, a supplementary exam is required.
The distributed evaluation obtained in previous courses, is not valid.
