Course Objective

The aim of this lecture is to study for the effects of small disturbances in the algebraic equations, integrals, linear and nonlinear differential equations.

Learning Outcomes of the Course Unit

1   Will be able to apply elementerary operations on the asymptotic expansions.
2   Will be able to approach the roots of a regular and singular perturbed algebraic equation.
3   Will be able to apply at least one regular perturbation method for a differential equation near the equlibruim point.
4   Will be able to apply at least one regular perturbation method for a differential equation near the limit cycle points.
5   Will be able to apply the method of matched for a linear differential equation near the boundary layer.
