I'm new to Maxima, and am having problem figuring out how to set up a
problem so Maxima will and solve it. Here's an example of a couple of
equations that I want to get symbolic solutions for:
f1: (Rb/Bmin) * B * (B - Bmin) * (1 - B/Bmax) - A * B * F = 0;
f2: (Rf/Fmin) * F * (F - Fmin) * (1 - F/Fmax) - A * B * F = 0;
res: solve ([f1, f2], [B, F]);
Now if I input just that, and try to solve it symbolically, Maxima hangs.
But if I set the constants to numeric values, as below, it will go
ahead and give me numeric solutions.
f1: (Rb/Bmin) * B * (B - Bmin) * (1 - B/Bmax) - A * B * F = 0;
f2: (Rf/Fmin) * F * (F - Fmin) * (1 - F/Fmax) - A * B * F = 0;
Bmin : 3000.0;
Bmax : 150000.0;
Fmin : 15000.0;
Fmax : 400000.0;
Rb : 0.05;
Rf : 0.08;
A : 1.0e-7;
res: solve ([f1, f2], [B, F]);
Can anyone know tell me I'm doing wrong here? Or where to look in the
manual?
Thanks,
James
