any thoughts on how to nondimensionlize my set of equations?
... or at the very least, on how to clean them up a bit? Here are the equations: p1'[t]==-k6 p1[t]-2*k7 p1[t]^2+2*k8 p1p1[t]+k5 (x1tot-x1p2[t]) p2'[t]==-k10 p2[t]-k1 p2[t] (x1tot-x1p2[t])+k2 x1p2[t]+k9 (x2tot- x2p1p1[t]) p1p1'[t]==k7 p1[t]^2-k8 p1p1[t]-k3 p1p1[t] (x2tot-x2p1p1[t])+k4 x2p1p1[t] x1p2'[t]==k1 p2[t] (x1tot-x1p2[t])-k2 x1p2[t] x2p1p1'[t]==k3 p1p1[t] (x2tot-x2p1p1[t])-k4 x2p1p1[t] where p1[t], p2[t], p1p1[t], x1p2[t], x2p1p1[t] are the variables, and k1, ..., kN and x1tot and x2tot are constants. In the end I want to find the steady states of the system (p1'[t]==p2'[t]==p1p1'[t]==x1p2'[t]==x2p1p1'[t]==0), but I'd like to make the equations as nice and easy to work with as possible, and I'm not quite sure how to do that. Simply setting the lefthand side to zero and solving gives me solutions that are pretty messy. As always, any thoughts that this great community might have would be most appreciated. Cheers, Dan
