Hello Radovan and all,

Do you have a trick to manage that system ?
Thanks in advance, Jean

Sorry Jean, I do not understand what did you mean by "trick".

Those are three linear first order ODE which are very often found in reaction kinetics. It seems to me that this would be no problem at all in numerical solving of them. Analytical solution should be also obtained by the appropriate method for such system.

Ra

Quite right Radovan about analytical methods.
