👉 In mathematics, a postnodal point is a critical point of a nonlinear differential equation. A postnodal point is a solution to an initial value problem for which the derivative of the solution at that point is zero. This condition ensures that the solution does not diverge or oscillate away from the equilibrium state. Postnodal points are crucial in studying solutions to nonlinear differential equations, as they provide insight into the stability and behavior of these solutions. In particular, postnodal points can help
