Hello,
i want to depict: Solidus/Liquidus curve equantions for solid solution system. Its a 2d parametric presentation.
File - New - Function plot - 2d parametric function plot
Parameter t from 0 to 1
X(t) = exp{50000/8,314*(1/t-1/1000)}-1/exp{50000/8,314*(1/t-1/1000)-50000/8,314*(1/t-1/1400)}-1
&
Y(t) = exp{50000/8,314*(1/t-1/1000)}-1/exp{50000/8,314*(1/t-1/1000)-exp(1/t-1/1400)}-1
The problem: it does not work. whats my failure?

Hi,
First, we do not use "{}" in formulas, so replace them with "()"
Second, by default, we use dot to indicate decimal digits instead of comma.
So the equations would be:
X(t) = exp(50000/8.314*(1/t-1/1000))-1/exp(50000/8.314*(1/t-1/1000)-50000/8.314*(1/t-1/1400))-1
Y(t) = exp(50000/8.314*(1/t-1/1000))-1/exp(50000/8.314*(1/t-1/1000)-exp(1/t-1/1400))-1
Another problem is, if t is from 0 to 1, there will be no data point. Actually, there will be no data until t equals to 9.
So I guess your "8,314" might be "8314"?
Anyway, there might be something else you need to fix in your formula.
