Comment:
Ubegrænset deltagerantal. Undervises fælles med MM507 Differentialligninger og MM512 Kurver og flader
Prerequisites:
None
Academic preconditions:
”Linear algebra” (MM505) (or ”Algebra and linear algebra” (MM538)) and ”Mathematical and numerical analysis” (MM533) should be known.
Course introductionTo introduce modelling of problems from science and engineering by ordinary differential equations and to analyse and solve these equations. The course will introduce analytic techniques to deal with parameterized curves and surfaces in three dimensions and give the students methods to visualize the geometric results obtained.
QualificationsHaving completed the course successfully, the student can be expected to
- analyze and organize a domain or a situation with reference to mathematical modeling
- recognize problems which can be modeled by differential equations
- “read” the qualitative properties described by a model
- construct a mathematical model for a concrete problem
- find solutions analytical or numerical to ordinary differential equations by application of anappropriate tool
- to relate the solutions to the original problem
- work analytically with the following concepts, understand the geometric content of and connections between these ideas:
- arc-length, curvature and torsion for curves in the plane and three-dimensional space
- regularity of a parameterization
- principal, Gaussian and mean curvatures for a surface in three-dimensional space
- geodesic curves on parameterized surfaces in three-dimensions
Expected learning outcomeAt the end of the course the student should be able to:
- formulate a differential equation as a model for a simple problem
- solve differential equations by methods taught in the course
- find steady states and analyse the asymptotic behaviour of simple systems of differential equations
- reproduce definitions and results, together with their proofs, in the geometry of plane- and space-curves and of surfaces in space, within the scope of the course's syllabus
- apply these results to examples
- formulate and present definitions, proofs and computations in a mathematically rigorous way
