Hi I am trying to solve a system of two nonlinear ordinary differential equations with initial conditions. The system is f'''(x)+2.4f(x)f''(x)-0.8(f')**2+z=0 z''(x)+2.4Pr[f(x)z(x)]'=0 with z(0)=0, z'(0)=0, f''(0)=0, f(0)=0, f'(10)=0 I use NDSolve end the message that gives me is: NDSolve::deql: The first argument must have both an equation and an initial condition. Can you help me; Gianna ipappa at mie.uth.gr
