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
