Method of dominant balance

The Method of Dominant Balance is a technique used in asymptotic analysis to approximate the solutions of differential equations and other mathematical problems, especially in the context of singular perturbation problems. This method is particularly useful when dealing with problems where the behavior of the solution changes dramatically in certain regions or under specific conditions. The key steps of the Method of Dominant Balance typically include: 1. **Identifying Scales**: First, identify the different terms in the equation and their respective scales.
