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 isosceles right triangles whose hypotenuse lies along the base. This hypotenuse has length = upper(x) – lower(x).
You can move this isosceles right triangle by sliding the MoveMe slider.
You can modify any of these parameters (functions, limits) at any time.
