Casio FX-991EX and FX-300ES

[Csaba Tizedes]

I have tried how can I solve with it simple ODE, and it works. Check the attachment. (Solving Clausius-Clapeyron ODE - the problem: what is the boiling temperature of water if the pressure is 2 bara). I can do it with my another CASIO with numeric integration but requires some iteration to find the solution (T_boiling= 393.6K= 120.4°C)

The greatest fault: Unfortunately the English is not selectable if I'll buy CE version.
