∫(log3x / 2x) (dx)
R is bounded below by the x-axis and above by the curve
y = 2cosx, Figure 11.1. Find the volume of the solid generated by
revolving R around the y-axis by the method of cylindrical shells
0(< or =) x(< or =) pi/2
limx→∞ ( 3x-2/3x+2 )^x
A solid of revolution and limit problem are solved.
