Key Topics to Revise
1
Basic Concepts and Classification
- A differential equation involves derivatives of dependent variable with respect to independent variable
- Order is determined by the highest order derivative present
- Degree is the power of the highest order derivative when equation is polynomial in derivatives
2
Formation of Differential Equations
- Differential equations are formed by eliminating arbitrary constants from family of curves
- Number of arbitrary constants equals the order of resulting differential equation
- Process involves successive differentiation to generate enough equations
3
Variable Separable Differential Equations
- Equations of form dy/dx = f(x)g(y) can be separated into dy/g(y) = f(x)dx
- Integration of both sides gives general solution
- Method works when variables can be completely separated
4
Homogeneous Differential Equations
- Equation dy/dx = F(x,y) is homogeneous if F(x,y) is homogeneous function of degree zero
- F(x,y) = G(y/x) for homogeneous functions of degree zero
- Substitute y = vx where v = y/x to reduce to separable form
