I have no experience with this sort of problem.
I've only ever made simple graphs before. This one requires special computer software.
For now, the problem is simple...
I have derived a formula for a simple model of a star:
I need to make a graph of a vs b.
This is where I'm begging you to help me. What (free) program could I use? Could anyone provide instructions on how to graph this with the program?
I thank you very very much in advance!
Positive. In these equations, r is radius, and r0, P0, and T0 are all positive constants. This is keeping in mind that the temperature, pressure, and density all decrease with radius.
After I graph it, I'll have to point out three regions of the graph (convectively stable, unstable and non-physical)
