Hi, this can not be solved! You have a first order ODE and you can specify only ONE initial condition. But you specify y[t]==1 for t=0..10 Sin[10] hope this helps, Daniel Narasimham wrote: > How to numerically Solve a differential equation like > [{ y'[ t] == 1 + 2 y[t], y[t + Sin[t]] == 1}, y, {t, 0, 10}] ; > > Should y[0] be assumed arbitrarily and then refined by some > sort of variable boundary value problem iteration? > > Basically :) does it make sense as the BC is function of a function? > > Regards, > Narasimham >
