Equilibrium points of 2nd ODE

  1. Feb 15, 2012 #1
    1. The problem statement, all variables and given/known data

    Find the equilibrium points for the following equation. Determine if the equilibrium points are stable and if stable,approximate the angular frequency.

    (i) d2y/dx2 = cosh(x).

    2. Relevant equations

    3. The attempt at a solution

    For equilibrium points, do we need to find dy/dx = 0 or d2y/dx2 = 0 or both?

    Thank you.
