If DE contains only ordinary derivatives of one or more unknown functions w.r.t single independent variable, it is said to be an

  • A.ODE
  • B.PDE
  • C.DDE
  • D.SDE

Answer: A

An ordinary differential equation (ODE) involves derivatives with respect to a single independent variable.

\[ \frac{d^{2}y}{dx^{2}} + 3\frac{dy}{dx} + 2y = 0 \]

When two or more independent variables appear and partial derivatives are involved, the equation is a PDE instead.
