A model for tumor growth is given by the Gompertz equation dV = a(b – In V)V dt where a and b are constants and V is the volume of the tumor measured in mm³. (a) Find a family of solutions for tumor volume V(t) as a function of time (t). Your answer will contain terms involving a and b and a third arbitrary constant. (b) Find the particular solution V(t) that has an initial tumor volume of V(0) = 1 mm³.
