State the order of the given ordinary differential equation. x d3y dx3 − dy dx 4 + y = 0 third order Incorrect: Your answer is incorrect. Determine whether the equation is linear or nonlinear by matching it with (6) in Section 1.1. an(x) dny dxn + an − 1(x) dn − 1y dxn − 1 + + a1(x) dy dx + a0(x)y = g(x) (6)
