Modifiable Solid: Isosceles Triangle (Modifiable) Cross Sections Parallel to yAxis
HOW TO USE:
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 triangles.
The base of this isosceles triangle has length upper(x) - lower(x).
You can use the slider to change the congruent base angles of this isosceles triangular cross section.
You can move this isosceles triangle by sliding the MoveMe slider.
You can modify any of these parameters (functions, limits) at any time.

TO EXPLORE IN AUGMENTED REALITY:
1) Open up GeoGebra 3D app on your device.
2) Go to the MENU (horizontal bars) in the upper left corner. Select OPEN.
In the Search GeoGebra Resources input box, type f97crzkb.
(Note this is the resource ID = last 8 digits of the URL for this resource.)
3) In the resource that uploads, zoom in/out if needed.
You can alter the functions upper(x), lower(x).
You can also move sliders a, b, MoveMe, Filling, and .
