Hi all,

I need to find a specific temperature which I named T2 to cross the zeroline in a plot but maple doesn't plot or give a solution at all. I'm very confused and also new with this software.

My code is as follows:

R = 8.314472;
> A = 1.935;
> B = 36.915*E-3;
>
> C = -11.402*E-6;
> P2 = 10*10^5;
> P1 = 101300;
> T1=365;
> Tc=425.1;
> Tw=T2/T1;
> Pc = 37.96*10^5;
> Pr1=P1/Pc;
