 Author Comment/Response Jigoro 03/21/13 03:11am Dear Community members, It is known that the solution to the problem z''(t)-z'(t)-2*z(t) = 0, where z(0)=3, z'(0)=0 is given by z(t) = Exp[2*t]+2*Exp[-t]. Yet, the commands s = NDSolve[{z''[t] - z'[t] - 2*z[t] == 0, z[0] == 3, z'[0] == 0}, z, {t, -100, 100}] Plot[Evaluate[z[t] /. s], {t, -100, 100}, PlotRange -> All] reveal a wrong solution (namely, the function z spikes up at a different value of t than it should be). Can you please help to find out the remedy to this issue? Best regards, Jigoro. URL: ,
