Prob. 2: A vector $\vec{V}$ is expressed in the frame A as $\vec{V} = \begin{bmatrix} 1 \\ -2 \\ 3 \end{bmatrix}$. Suppose frame B is obtained by rotating the frame A using 3($\theta_3$)-2($\theta_2$)-1($\theta_1$) Euler angles, where $\theta_3=30^\circ$, $\theta_2 = 20^\circ$, and $\theta_1 = 10^\circ$ are three Euler angles. (a) What is the vector $\vec{V}$ expressed in the frame B. (b) Find the Euler axis $\vec{e}$ and Euler rotational angle $\phi$ corresponding to this coordinate rotation from the frame A to frame B. (c) Compute the direction cosine matrix using $\vec{e}$ and $\phi$. Use this direction cosine matrix to show the vector $\vec{V}$ expressed in the frame B. Compare your result with that in (a). (d) Find the quaternion corresponding to this coordinate rotation from the frame A to frame B. (e) Compute the direction cosine matrix using the quaternion. Use this direction cosine matrix to show the vector $\vec{V}$ expressed in the frame B. Compare your result with that in (a) and (c).

a. In our basic model, we assumed that the labor supply curve was vertical. Using solid microeconomic reasoning, explain why an increase in the real wage would have no effect on aggregate labor supply. b. Is there empirical evidence to suggest that a vertical labor supply curve is plausible? Explain. c. Suppose the price of goods (P) rises. What happens to the equilibrium real wage, nominal wage, and quantity of employment? Explain why. What happens to equilibrium output? Explain why.
