A spherical vessel of radius r = C (in m) is filled with liquid at a rate of 0.1 m3/s. What is the rate of change of depth of liquid when the depth is one-half of the radius? V = 3 (3r - h) is the volume of a spherical cap of depth h. For the function y(x) = xsincx, use logarithmic differentiation to determine an expression for dy dx
