This applet will generate a solid with a square cross section. [br][br]Set the function, f(x), and lower/upper bounds, a and b, using the input boxes.[br][br]Checking 'Show Solid' will reveal the edges of the shape generated by your chosen function. Move slider 's' to extrude the shape over the chosen bounds.[br][br]Checking 'Show Prisms' will show an approximation of this volume using square prisms. The slider 'n' will change the number of prisms in your approximation.
