I need to solve systems of numerical equations. I encountered a problem, where one of the parameters (tau[p3]) become FREE, see Maple worksheet attached.
That was clearly not expected.
I spent about 40 mintues to inspect what the problem is, eventually, I find that fsolve works perfectly.
Though fsolve would be the "first" choice for solving floating point problems. I really dont see why the simple "solve" syntax can not work. It is acting strange. And why is *tau[p3]* FREE, not the others?
Could this be a bug? Or maybe is just WRONG to use solve?
