Key Topics to Revise

1

Basic Concepts - Order and Degree

  • A differential equation involves derivatives of dependent variable with respect to independent variable(s)
  • Ordinary differential equations have derivatives with respect to only one independent variable
  • Order is the highest derivative present in the equation
2

Solutions of Differential Equations

  • General solution contains arbitrary constants equal to the order of equation
  • Particular solution has no arbitrary constants, obtained by giving specific values
  • Solution curve represents the graph of solution function
3

Formation of Differential Equations

  • Start with equation containing arbitrary constants (parameters)
  • Differentiate enough times to match number of constants
  • Eliminate constants from the system of equations
4

Solving Simple Differential Equations

  • Variable separable equations: dy/dx = f(x)g(y)
  • Separate variables: dy/g(y) = f(x)dx
  • Integrate both sides independently
