Revision Notes — Differential Equations
Key concepts, formulas, and definitions from Differential Equations for AP EAPCET Mathematics preparation.
Key Topics to Revise
Basic Concepts and Definitions
- A differential equation involves derivatives of dependent variables with respect to independent variables
- Order is determined by the highest derivative present
- Degree is the power of the highest order derivative (when polynomial form)
Formation of Differential Equations
- To form differential equation from general solution, differentiate and eliminate arbitrary constants
- Number of differentiations = number of arbitrary constants
- Final equation should be free from arbitrary constants
Variable Separable Method
- Applicable when equation can be written as dy/dx = f(x)g(y)
- Separate variables: dy/g(y) = f(x)dx
- Integrate both sides and add constant of integration
Homogeneous Differential Equations
- Equation of form dy/dx = f(x,y)/g(x,y) where f,g are homogeneous functions of same degree
- Substitute y = vx, so dy/dx = v + x(dv/dx)
- Equation becomes separable in variables v and x
