To do this, you need `min_symbolic` and `max_symbolic`, as in #6949. But
I don't think this is in the documentation for plotting anywhere.
{{{
M = matrix([[1,-1],[-1,1]])
f1(p) = (M[1,0] - M[0,0])*p+M[0,0]
f2(p) = (M[1,1] - M[0,1])*p+M[0,1]
P = plot([f1,f2],(p,0,1),linestyle='--')
P += plot(min_symbolic(f1(p),f2(p)),(p,0,1),color='red')
show(P,axes_labels=['$p$','Exp.'])
}}}
Notice that
{{{
P += plot(min_symbolic(f1,f2),(p,0,1),color='red')
}}}
and
{{{
P += plot(min(f1(p),f2(p)),(p,0,1),color='red')
}}}
don't work properly. I could even consider the first one a bug...
Putting in component 'graphics' because it's more likely these people will
write documentation for this than symbolics or doc people!
