Key Topics to Revise

1

Fundamentals of Differential Equations

  • A differential equation contains derivatives like dy/dx, d²y/dx², etc.
  • Order is determined by the highest derivative present
  • Degree is the power of the highest order derivative after clearing fractions and radicals
2

Formation of Differential Equations

  • Eliminate arbitrary constants by differentiation
  • Number of differentiations = number of arbitrary constants
  • Use algebraic manipulation to eliminate constants
3

Variable Separable Differential Equations

  • Type 1: dy/dx = f(x) - Direct integration
  • Type 2: dy/dx = f(x)g(y) - Separate variables and integrate
  • Rearrange to get all x terms on one side, all y terms on other
4

Homogeneous Differential Equations

  • Form: dy/dx = f(y/x) where f is homogeneous of degree zero
  • Substitute y = vx, where v is a function of x
  • This gives dy/dx = v + x(dv/dx)
