This applet is designed to help you visualize the solids of revolution obtained by revolving various functions about the x-axis. [br][br]You can enter any function you like into the input box for f(x).[br]You can adjust the upper and lower bounds with the sliders for a and b.[br]The slider for Alpha allows you to control how far the function is revolved around the axis. This is useful for visualizing how the revolution creates the solid.[br][br]In the lower left side of the screen is a play button that will allow you to animate the revolution.
