Examine the following functions for the existence of directional derivatives and differentiability at (0, 0). The expressions below give the value at \((x, y) \neq (0, 0)\). At (0, 0), the value should be taken as zero: (i) \(xy\frac{x^2 - y^2}{x^2 + y^2}\) (ii) \(\frac{x^3}{x^2 + y^2}\) (iii) \((x^2 + y^2)\sin\frac{1}{x^2 + y^2}\) (iv) \(|xy|\)

The circles $r = \frac{1}{\sqrt{2}}$ and $r = \sin\theta$ are graphed below. Use polar coordinates to describe the region that lies outside the circle $r = \frac{1}{\sqrt{2}}$ and inside the circle $r = \sin\theta$. Ensure your bounds on $\theta$ are in the interval $[0, 2\pi)$. $\frac{1}{\sqrt{2}} \le r \le \sin(\theta)$, and $\boxed{} \le \theta \le \boxed{}$

A viscosity motor/pump is shown in figure below. The rotor is concentric within a stationary housing. The clearance h between the housing and the rotor is small compared to the width w and radius R of the rotor. A seal divides the clearance space as shown. When the device is operated as a motor, the viscous liquid is introduced at the high-pressure side of the seal and leaves at the low-pressure side of the seal. This flow causes the rotor to turn and produce power. For R is 1.75 ft, h is 0.50 in., w is 1.9 ft, \(\omega\) is 18 rpm, and a flow rate of 1.5 ft³/min, find the power output of the rotor. The fluid is 60 °F, SAE 30 crankcase oil. The dynamic viscosity of the oil is 0.116 lbm/(ft\(\cdot\)s). Neglect gravity. Model the flow as the fully developed flow between the parallel plates.
