I have this problem and I want to solve this and the conditions are:
when p[r] = 0 we have the radius of the star;
and after this lim r-> \infinity R[r] = 0.
How can I solve this problem? I mean how can I write a looping for solve the equations inside and outside the star simultaneously.
There is a problem with your code. You use the strange symbol r\362, that I had never seen, that typesets almost the same as r^2. What was your intention?
r\362
r^2
Also, equations are written with ==, not with =.
==
=
