1. convert the equation y'''(x)-3y'(x)-xy=0 with initial conditions y(0)=0.8064, y'(0)=1.03598, y''(0)=-0.09998 into 3 first order equations using
1)euler forward difference method
2)second order runga kutta method
k1=hf(x,y)
k2=hf(xn+h/2,yn+k1/2)
yn+1=yn+k2
find numerical solution y at x=0.1, 0.2, 0.3 step length h=0.1

very difficult to get help on line with this horrible numerical ODE staff

my suggestion

visit

this is a self teach book which definitely covers your question together with other topics which you might come across.
3. Reduce the equation first watch this you tube video I guess it might help

then to use Euler method is simple I guess after that
