Desmos 3D Graphing Features

The video introduces the new Desmos 3D graphing calculator, demonstrating how to plot points and graph surfaces in three dimensions. It covers features like rotating graphs, adjusting axis scaling, and using sliders for dynamic graphing. The tutorial also shows how to extend 2D equations into 3D and explores advanced graphing techniques, making the tool versatile for various mathematical explorations.

How can you access the Desmos 3D graphing calculator?

• By visiting desmos.com/3D

• By downloading an app

• By subscribing to a newsletter

What is the default range for the axes in the Desmos 3D graphing calculator?

• From -1 to 1

• From -20 to 20

• From -5 to 5

• From -10 to 10

What feature allows you to change the appearance of surfaces in the graph?

• The wrench tool

• The grid settings

• The axis menu

• The color palette

Which equation represents a surface that can be manipulated using sliders for A and B?

• Z = ax^2 + by^2

• Z = sin(x) + cos(y)

• Z = x^2 - y^2

• Z = x + y

What happens when you extend a 2D equation to 3D in Desmos?

• The equation becomes static

• The graph remains unchanged

• The graph becomes dynamic and interactive

• The equation is deleted

Which of the following is a feature of the Desmos 3D graphing calculator?

• Only 2D graphing

• Dynamic graphing with sliders

• Static graphing

• Limited to linear equations

What is the purpose of the 'extend to 3D' option?

• To add color to the graph

• To create a 3D representation of a 2D equation

• To simplify the equation

• To remove the Z-axis

Which equation includes sine functions for all three variables?

• x^2 + y^2 + z^2 = a

• x^2 + y^2 + z^2 + sin(4x) + sin(4y) + sin(4z) = a

• sin(x) + sin(y) + sin(z) = a

• x + y + z = a

What can you do with the toolbar in the Desmos 3D graphing calculator?

• Only change colors

• Only adjust the grid
