Learning Outcomes
On successful completion of this module students should be able to:
Demonstrate an understanding of the meaning of asymptotic solutions in the appropriate context and how to interpret these;
Solve simple linear and nonlinear ordinary and partial differential equations by asymptotic methods;
Illustrate with suitable examples the occurrence of asymptotic phenomena in mechanics.
Brief description
Many mathematical problems arising in mechanics, may be formulated in terms of differential equations. However, as a rule, such problems pose new challenges from the mathematical point of view. Therefore, the simplest limit cases, which allow analytical solutions, are of particular importance. The aim of the asymptotic approach is to simplify the mathematical problem under consideration.
