Prove the following identity for $x \neq 0$:\\ $\sin x + \cos^{-1}(-x) = \frac{\pi}{2}$ \\ Let $\cos^{-1} x = \alpha$. Identify $\alpha$. Choose the correct graph below.\\ Let $\cos^{-1}(-x) = \beta$. Identify $\beta$. Choose the correct graph below.\\ Express $\beta$ in terms of $\alpha$.\ $\beta = \boxed{}$ \\ (Type an expression using $\alpha$ as the variable. Type an exact answer in terms of $\pi$.)\ Simplify the expression $\sin x + \cos^{-1}(-x)$. Remember $\cos^{-1} x = \alpha$ and $\cos^{-1}(-x) = \beta$.\ $\sin x + \cos^{-1}(-x) = \boxed{}$ \\ Is the proof complete?\ $\circ$ A. Yes, because $\alpha + \beta = \frac{\pi}{2}$ \\ $\circ$ B. No, because $\alpha + \beta \neq \frac{\pi}{2}$

3. How far does the spindle move away from the anvil for one anticlockwise revolution of the thimble of a metric outside micrometer? 4. Why is it undesirable to store a 0-25 mm outside micrometer with the measuring faces touching each other? 5. If the thimble on a 0-25 mm outside micrometer is rotated anticlockwise for one marked division, how far apart will the measuring faces move? 6. What type of scale is provided on the SLEEVE of some metric micrometers to allow a measurement to an accuracy of 0.001 mm? 7 What check should be carried out on a 0-25 mm outside micrometer each time it is used? 8. What type of spanner is required to adjust the zero position of the datum line on the sleeve scale of a micrometer? 9.

In a rigid body, consisting of three mass points and one rigid, massless linkage, the masses and their positions in the solid system are: 3m at the place (x = 2a, y = 2a, z = 0), 3m at the place (x = -2a, y = -2a, z = 0), and 5m at the place (x = 0, y = 0, z = 3a). Here, m and a are constants. Calculate the components of the angular momentum in the body-fixed system with respect to the origin, if the vector of the angular velocity in the body-fixed system at a point in time shows the direction of the surface diagonal in the yz-plane and has the magnitude Ï‰.
