Learning outcomes o familiarize students with the key tools of Linear Algebra (Matrix Calculation, Determinants, Eigenvalues and vectors) and Numerical Analysis (Approximation of roots of algebraic equations, interpolation functions, Numerical integration, Numerical solution of differential equations).
Students should be able to:
- Solve a system of linear equations
- Find the Inverse of a matrix using the Gauss-Jordan Method
- Find the Null space and image space of a matrix
- Apply the Theory of Eigenvalues and Eigenvectors to solve differential equations
- Numerical approximation of the roots of an equation by Newton's method and bisection method.
- Numerical approximation of a function using Lagrange interpolation
- Numerically integration of a real-valued function

Teaching Methodologies and Assessment Criteria The curricular unit is divided into two parts:

- The Linear Algebra part will work during the first 7 weeks, being evaluated by two minitestes (March 12 and April 5, with 4 and 6 values, respectively);

- The numerical part will work in the second half of the semester, being evaluated by two mini-tests (May 9 and June 11, with 4 and 6 values, respectively). The student, if you wish, can choose to work in Python by implementing Numeric algorithms. In this case, in each of the two minitestes, one of the questions will be replaced by another one focusing on the tasks performed in Python and will be worth 1 value.

If the sum of the evaluations of the four minitestes is equal to or greater than 9.5 values, the student is exempt from the final exam. If the sum is less than 5.5 values, the student will be Not Admitted.

The student who has chosen Python may choose to keep the grade obtained in the evaluation of these two values, taking the exam for 18 values.
Language Portuguese. Tutorial support is available in English.
