Présentation
The 1st applied maths course is desgined to provide the student with analytical tools for physics, such as ODE solutions, perturbations methods, Lyapunov exponents...
It is followed by the 2nd applied maths courses which focuses on the (mainly linear) partial differential equations for physics (fluid mechanics in particular).
Pré-requis nécessaires
Integration of linear ordinary differential equations.
Objectifs
To acquire the mathematical tools necessary for many problems in the engineering sciences (aerodynamics or hydrodynamics, calculation of structures, etc.) or useful in Master 2 in these fields.
Compétences visées
- Know the basic methods for discussing solutions of ordinary differential equations.
- Develop approximate solutions in the form of asymptotic developments when a small parameter can be identified in the equations.
