Mathematics III

Enrollment into the second academic year.

The prerequisite for the theoretical exam is a positive result of the written exam.

Homework may also be one of obligations.

and L_2[-a,a], pointwise convergence of trigonometric Fourier series.

Ordinary differential equations (DE): linear first order DE, separation of variables, exact DE. Existence theorem for the first order DE.

Existence theorem for a system of linear first order DE's. Homogeneous linear second order DE: Wronskian, linear DE with constant coefficients.
Nonhomogeneous linear second order DE: variation of parameters. DE with constant coefficients: particular solutions. Mechanical (damped and non-damped) oscillations, resonance. Linear DE's of higher order.

Systems of linear first order DE's. Systems with with constant coefficients: solving the homogeneus system using eigenvalues and eigenvectors. The exponential function of a square matrix, variation of parameters.

Line integrals, potential fields, Green's formula in the plane.

Surfaces in R^3, the tangent plane, area of a surface. Surface integrals and the flux of a vector field. Nabla (del) operator, gradient, divergence, curl. Gauss-Ostrogradski and Stokes' theorem. Operations with nabla, Laplacian (also in cylindric and spherical coordinates).

Students learn advanced topics in Mathematical Analysis: multiple integrals, Fourier series, ordinary DE, vector analysis, calculus of variations. Mathematics III
is a basic course for physicists.

Knowledge and understanding:
We expect that students know important definitions and theorems, understand (and ideally be able to replicate) at least the easier proofs, and be able to apply this knowledge , e.g. in Mathematical Physics.

Application:
This course is a prerequiste for Mathematics IV, Numerical methods, Mathematical physics, Mechanics and other courses.

Reflection:
Students master some advanced topics in Mathematical Analysis and are able to apply them in physics.

Transferable skills:
Students learn to understand the usefulness of the abstract approach, are able to connect the acquired knowledge with what they already mastered. They also learn to use other written sources and the internet. They are able to identify and solve problems, hand in homework on time, and memorize the important topics.

Lectures, tutorials, homework (optional).

Written exam or 2 midterm exams instead of the written exam
Oral exam or theoretical test, homework
grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
