The exam will take place on 23.01, at 14.00-17.00 PM, in HIL G41.
Students will be able to take the exam either in German or in English.
Electronic devices (such as, but not limited to, smartphones, calculators, tablets, laptops, etc.) are not allowed to use during the exam. Students are allowed to bring course notes to the exam, either printed or hand-written. Students are also allowed to bring summaries of the course notes, or summarised formula sheets. Students are NOT allowed to bring the exercises and the solutions from this course to the exam (either printed, or hand-written). Students can also bring formula sheets, such as standard solutions to ODE, typical basis in which to represent solutions to PDEs, fourier series, etc.
For the exercise classes, see the section Exercise classes.
In this lecture we treat problems in applied analysis. The focus lies on the simplest cases of three fundamental types of partial differential equations of second order: the Laplace equation, the heat equation and the wave equation.
