2. If \( u=\tan ^{-1} \frac{x^{3}+y^{3}}{x-y} \), prove that \( x \frac{\partial u}{\partial x}+y \frac{\partial u}{\partial y}=\sin 2 u \). 3. Verify Euler's theorem for the functions (i) \( u(x, y)=a x^{2}+2 h x y+b y^{2} \). (ii) \( u=\frac{x-y}{x+y} \). (iii) \( x^{3}+y^{3}+3 x^{2} y+3 x y^{2} \). 4. If \( u=x^{2} y+y^{2} z+z^{2} x \), show that \( u_{x}+u_{y}+u_{z}=(x+y+z)^{2} \). 5. Write the Euler's theorem for three variables.

11. In an epicyclic gear of the sun and planet type, the p.c.d. of the internally toothed ring is to be as nearly as possible 220 mm, and the teeth are to have a module of 4. When the ring is stationary, the spider, which carries three planets of equal size, is to make one revolution for every five revolutions of the driving spindle carrying the sun wheel. Determine suitable numbers of teeth for all the wheels and the exact diameter of the pitch circle of the ring. If a torque of 12 N m is applied to the spindle carrying the sun wheel, what torque will be required to keep the ring stationary? (U. Lond.) (Answer: 56, 21, 14; 224 mm; 48 N m)
