Re: Question from a biologist


Dear tnad,

could you describe your problem in more detail, e.g. give an example?

One way to set something to zero in a sea of equations is

equations/.{x[t]->x0,D[x[t],t]->0}.

Maybe this is useful.

Bye
Ben

Right now, I have to look for the first derivative of every variable in a sea of differential equations and set it to zero. Is there a more "elegant" way to do this in mathematica?
