exponentials volume of revolution
Shows the solid resulting from revolving the region bounded by exp(x), exp(-x), and x=ln(4) around the y-axis.
The 3D model can be rotated in any direction using the tool that looks like two semi-circles with arrows at each end intersecting at right angles(upper tool bar) or it can be rotated around the z-axis using the tool that looks like an arrow bent into a circle (lower tool bar).
