DSolve does not solve a differential. No error message either.

Posted 11 years ago

Hi,

I tried to solve a differential equation by using DSolve. I set up the equation and executed it, but Mathematica just output the differential equation again without any error message. Does anyone know what happened? How could I solve this differential equation?

   DSolve[{V'[t]==A ?p (V0 + g t- V[t]) Exp[B (Vg - V[t])] -kr  V[t],V[0]==0},V[t],t]

When DSolve cannot find a solution it will return unevaluated. Do you expect that there should be an analytic solution?

Do you need an analytic solution? If not, then make use of NDSolve with numerical values of your parameters.
