Cross Sectional Specials (Calculus): GeoGebra 3D with AR Demos (iOS)

Below is a list of quick screencasts that illustrate several 3D surfaces that can be formed with specific cross sections that are parallel to the yAxis. [br][br]For each GeoGebra applet found in each resource link below, the upper function, lower function, and limits of integration are ALL MODIFIABLE. [br][br][b]Enjoy! [/b][br][br]All screencasts shown here were recorded on an iPadPro (larger screen) or iPhone 10S Max (smaller screen).

Cross Sections parallel to yAxis are squares.
