Let y(x) be the solution of the differential equation \frac{d^2 y}{d x^2}-4 \frac{d y}{d x}+4 y=0 with initial conditions y(0) = 0 and \left.\frac{d y}{d x}\right|_{x=0}= 1 Then the value of y(1) is ________.
The solution of the given differential equation is of the form
y(t)=\left(C_1+C_2 x\right) e^{2 x}
Given that y (0) = 0, so,
0=C_1
Therefore,
\begin{aligned}& y(t)=C_2 x e^{2 x} \\& y^{\prime}(t)=C_2 e^{2 x}+2 C_2 x e^{2 x}\end{aligned}
Given that y′(0) = 1, so
1=C_2Therefore,y=x e^{2 x}
Thus y(1) = e²= 7.38
