    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
    5 decimal points. PLEASE HELP!!!!

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

    my suggestion

    visit

    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
