Base Knowledge
Solving equations and inequations involving real functions of one variable.
Calculation of derivatives of real functions of one variable (knowledge acquired in Mathematical Analysis I)
Matrix calculus: matrix operations and calculation of the inverse of a matrix (knowledge acquired in Mathematical Analysis I)
Teaching Methodologies
Classes are taught on a theoretical-practical basis.
The expository methodology is used to present the concepts of the curricular unit, supported by exercises to apply the concepts transmitted. Some of these exercises are based on real-life practical problems.
Learning Results
Goals:
Provide students with some existing numerical methods and techniques for solving concrete problems, which occur in the most diverse areas, and which are not always solved in a direct (analytical) way.
Introduce the discussion of the numerical results obtained.
Skills:
Develop the ability to select the methods that best adapt to the resolution of various problems by studying their efficiency, applicability and stability.
Interpret the numerical results obtained.
