    Hey hamidamini.

    My suggestion is that if you can't separate the y variable against the others, then you should use implicit differentiation to get dy/dx and then do a numerical integration based on these values.

    Are you familiar with numerical integration?

    Hi,
    Any good drawing program that can handle implicit functions is what you want. One such free program can be found at Graph | Plotting of mathematical functions Here is a sample (I had no idea what values you have for Ik and rs):
