4y^{''}+4y^'+y=0,y(0)=3,y^'(0)=-2

4 y^{^{''}} + 4 y^{^{'}} + y = 0, y (0) = 3, y^{^{'}} (0) = - 2

y = 3 e^{- \frac{t}{2}} - \frac{e ^{- \frac{t}{2}} t}{2}

Solution steps

4 y^{''} (t) + 4 y^{'} (t) + y = 0

Solve linear ODE:

y = 3 e^{- \frac{t}{2}} - \frac{e ^{- \frac{t}{2}} t}{2}

y = 3 e^{- \frac{t}{2}} - \frac{e ^{- \frac{t}{2}} t}{2}
