The matrix $A = \begin{bmatrix} -6 & 6 \\ -\frac{3}{2} & -6 \end{bmatrix}$ has the following eigenvalues and eigenvectors: $\lambda_1 = -6 + 3i$ with $\vec{v}_1 = \begin{bmatrix} -2i \\ 1 \end{bmatrix}$. and $\lambda_2 = -6 - 3i$ with $\vec{v}_2 = \begin{bmatrix} 2i \\ 1 \end{bmatrix}$. Consider the system $x_1' = -6x_1 + 6x_2$ $x_2' = -\frac{3}{2}x_1 - 6x_2$ 1. Determine a fundamental set (i.e., linearly independent set) of solutions for the system, where the fundamental set consists entirely of real solutions. Enter your solutions below. Use $t$ as the independent variable in your answers. $\vec{x}^{(1)}(t) = \begin{bmatrix} \\ \end{bmatrix}$ and $\vec{x}^{(2)}(t) = \begin{bmatrix} \\ \end{bmatrix}$ 2. Write the general real solution for the linear system (write "c1" and "c2" for $c_1$ and $c_2$) $x_1(t) =$ $x_2(t) =$

Let I be an open interval containing the point x ? R. Suppose that f? C²(I) and K is a number such that $|f''(c)| ? K$ for all c? I. (a) Use Taylor's Theorem to prove that if h > 0 is such that x + h is in I, then $\left| \frac{f(x+h) - f(x)}{h} - f'(x) \right| ? Ch$ where C is a constant independent of x and h. (b) As a consequence of what you proved in part (a), Explain how we usually interpret this result. $\frac{f(x+h) - f(x)}{h} - f'(x) = O(h)$ as $h ? 0^+.$
