Hi,
i have to reduce the order of a 2nd order differential equation, to solve it with a numerical method.
The equation is:
\ddot{r}+a\dot{r}+\frac{b}{r^{2}}=0
with a,b\geq0
I tried to reduce it substituting \dot{r}=v, but i don't know what to do with the term \frac{b}{r^{2}} .
Can someone explain me what i should do?
Thank you,
J.
