Use the RK4 method to approximate y(0.2), where y(x) is a solution of the initial-value problem $y^{\prime \prime}-2 y^{\prime}+2 y=e^{t} \cos t, \quad y(0)=1, y^{\prime}(0)=2$. First use $h=0.2$ and then $h=0.1$.

Given that

$$a = \left( \begin{array} { r } { 2 } \\ { - 2 } \\ { 1 } \end{array} \right) , b = \left( \begin{array} { l } { 1 } \\ { 1 } \\ { 2 } \end{array} \right) , c = \left( \begin{array} { r } { 3 } \\ { - 5 } \\ { 1 } \end{array} \right)$$

and

$$d = \left( \begin{array} { r } { 3 } \\ { - 3 } \\ { 2 } \end{array} \right)$$

, calculate (a)

$$a \cdot ( b + c )$$

(b)

$$( b - a ) \cdot ( d - c )$$

(c)

$$( b + d ) \cdot ( 2 a )$$
