🔍 Differential Equations at a Glance
| Type | Standard Form | Solution Method |
|---|---|---|
| Separable Variables | dy/dx = f(x)g(y) | ∫(1/g(y))dy = ∫f(x)dx |
| Linear First-Order | dy/dx + P(x)y = Q(x) | Integrating factor: e^(∫P(x)dx) |
| Homogeneous Second-Order | ay'' + by' + cy = 0 | Characteristic equation: ar² + br + c = 0 |
| Non-Homogeneous | ay'' + by' + cy = f(x) | General + Particular solution |
