  • Solve:

    • \[
      y”-3y’+2y=0; y(0)=0, y'(0)=1;
      \]
    • \[
      y”+4y’+4y=0; y(0)=0, y'(0)=1;
      \]
    • \[
      y”+y=0; y(0)=0, y'(0)=1;
      \]
  • Solve:

    • \[
      y”-3y’+2y=te^t-e^{2t}; y(0)=0, y'(0)=1;
      \]
    • \[
      y”+4y’+4y=t-e^{-2t}; y(0)=0, y'(0)=1;
      \]
    • \[
      y”+y=\cos(t)+t; y(0)=0, y'(0)=1.
