y^{''}+4y=2e^{2t},y(0)=1,y^'(0)=0

y^{^{''}} + 4 y = 2 e^{2 t}, y (0) = 1, y^{^{'}} (0) = 0

y = \frac{3}{4} cos (2 t) - \frac{1}{4} sin (2 t) + \frac{1}{4} e^{2 t}

Solution steps

y^{''} (t) + 4 y = 2 e^{2 t}

Solve linear ODE:

y = \frac{3}{4} cos (2 t) - \frac{1}{4} sin (2 t) + \frac{1}{4} e^{2 t}

y = \frac{3}{4} cos (2 t) - \frac{1}{4} sin (2 t) + \frac{1}{4} e^{2 t}
