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

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

y = - 3 e^{t} + 4 e^{t} t + \frac{e ^{t} t ^{3}}{6} + 4

Solution steps

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

Solve linear ODE:

y = - 3 e^{t} + 4 e^{t} t + \frac{e ^{t} t ^{3}}{6} + 4

y = - 3 e^{t} + 4 e^{t} t + \frac{e ^{t} t ^{3}}{6} + 4
