Enter any [b]UPPER FUNCTION[/b] (labeled upper(x)).[br]Enter any [b]LOWER FUNCTION[/b] (labeled lower(x)).[br]Enter your [b]lower and upper limits of integration[/b] ("a" and "b", respectively).[br][br]Slide the [b]FILLING[/b] slider all the way to the left. [br]For this solid, note how cross sections parallel to the yAxis are sections of [color=#ff7700][b]parabolas[/b][/color].[br]The [b]latus rectum[/b] of each parabolic cross section has length [b]upper(x) - lower(x)[/b]. [br][br]You can move this [color=#ff7700][b]parabolic cross section[/b][/color] by sliding the [b]MoveMe[/b] slider. [br][br]You can modify any of these parameters (functions, limits) at any time.

1) Open up GeoGebra 3D app on your device. [br][br]2) Go to the [b]MENU [/b](horizontal bars) in the upper left corner. Select OPEN.[br] In the Search GeoGebra Resources input box, type [b]jufvgyup[/b]. [br] (Note this is the resource ID = last 8 digits of the URL for this resource.)[br][br]3) In the resource that uploads, zoom in/out if needed. [br] You can alter the functions upper(x), lower(x).[br] You can also move sliders a, b, MoveMe, Filling, and [br] (Be sure to leave everything else alone.)[br]
