The applet will allow you to create piecewise-defined functions that will create the profile (cross-section) of your goblet. The applet will also show you the surfaces obtained by revolving the goblet profile around an axis of rotation.
- Type a function of into the input box: . (no implicit functions and no .)
- Move points C and D to choose an axis of rotation.
- Move points A and B to select a segment of your function for rotation.
- Either drag the angle slider by hand to revolve your function segment around your axis or click the triangle to revolve automatically.
