Hi,
I am stuck on the initial steps of this problem - its been a while since my diff. eq course.
I need to reduce this into a system of three equations then apply a 4th order runge kutta method to solve.
f'''+f*f''=0
Boundary conditions:
f'(0)=f(0)=0
f'(infinity)=0
A. Reduce this equation to a system of three first order equations, with associated boundary conditions.
Am I on the right track?
(equation 1) f'=g
(2) g'=h
(3) h'=-f*h
how to apply boundary conditions?
