How it works ?
Enter any UPPER FUNCTION (labeled upper(x)).
Enter any LOWER FUNCTION (labeled lower(x)).
Enter your lower and upper limits of integration (“a” and “b”, respectively).
Slide the FILLING slider all the way to the left. For this solid, note how cross sections parallel to the yAxis are regular heptagons whose side lies along the base. This side has length = upper(x) – lower(x).
You can move this regular heptagon by sliding the MoveMe slider.
You can modify any of these parameters (functions, limits) at any time.
