 Author Comment/Response Andrew R 10/18/12 11:32pm I am trying to solve any initial value problems with DSolve. if i use the input DSolve[y''[t] + 4 y'[t] + 4 y[t] == Sin[t], y[t], t] i get the solution in terms of C1 and C2 now i am trying to get a solution that satisfies y[0]=1 and y'[0]=0 how do i put the initial conditions to the DSolve command i tried this way DSolve[{y''[t] + 4 y'[t] + 4 y[t] == Sin[t], y[0] == 0}, y[t], t] but i get the error DSolve::deqn: "Equation or list of equations expected instead of True in the first argument {\!\(4\\\ y[t] + 4\\\ \*SuperscriptBox[\"y\", \"\[Prime]\", MultilineFunction->None][t] + \*SuperscriptBox[\"y\", \"\[Prime]\[Prime]\", MultilineFunction->None][t] == Sin[t], True\)}." Can anyone help me? URL: ,
