## Learning outcomes

After finished course a student should be able to

• recognize and use the basic concepts of linear algebra: vectors and their operations, straight lines and planes, linear dependence and independence, base vectors, linear transformations, matrices and determinants, eigenvalues and eigenvectors, quadratic forms.
• recognize and use the basic concepts of differential multivariable calculus: partial derivative, differentiability, differential, gradient, directional derivative, functional matrix and functional determinant.
• understand and explain the interaction between linear algebra and differential calculus, e.g. in connection with linearization of functions or analysis of the stationary points of multivariable functions.
• More precisely, after finished course the student should be able to:
• solve geometric problems involving points, lines and planes by means of dot and cross product.
• apply chain rules on partial derivations and decide whether a function satisfies a certain partial differential equation.

Systems of linear equations and matrices; determinants, Cramerís rule, geometric interpretation of determinants. Vectors and geometry in two and three dimensions, dot product, cross product. Matrices as linear transformations from Rn to Rm. The least-squares method. Quadratic forms and diagonalization. Functions of several variables; partial derivatives, gradient, chain rule. Differentials. Curves and their parametrization in R2 and R3. Extreme value problems, the method of Lagrangeís multipliers. Implicit functions. Taylor approximation.
