3D Graphing Software Functions

The video tutorial demonstrates how to use 3D graphing software to visualize functions of two variables. It introduces the 3D Calc Plotter from the NSF website, explaining the Java and JavaScript options. The tutorial guides viewers through graphing various functions, including square root, division, sine, and quadratic functions, while exploring different graphing options like zoom, transparency, and saving graphs as PNG files.

What are the two options available for the 3D graphing software?

• Java and Flash

• Java and JavaScript

• Python and JavaScript

• HTML and CSS

Which function is used to graph the first surface?

• f(x, y) = x^2 - y^2

• f(x, y) = x^2 + y^2

• f(x, y) = sqrt(x^2 + 2y^2)

• f(x, y) = x + y

What feature allows you to change the transparency of the surface?

• Zoom buttons

• Magnifying glass

• 3D goggles button

• Double arrows

How can you save the graph as an image file?

• By clicking the save button

• By using the print screen key

• By clicking the three horizontal bars and selecting save as PNG

• By right-clicking the graph

Which function is graphed as the second surface?

• f(x, y) = x^2 + y^2

• f(x, y) = 1 / (1 + x^2 + y^2)

• f(x, y) = y^2

• f(x, y) = sin(x)

What is the third function graphed in the tutorial?

• f(x, y) = tan(x)

• f(x, y) = cos(x)

• f(x, y) = x^2

• f(x, y) = sin(x)

Which function is graphed as the fourth surface?

• f(x, y) = y^2

• f(x, y) = x - y

• f(x, y) = x^2

• f(x, y) = x + y

What is the fifth function graphed in the tutorial?

• f(x, y) = (x - y)^2

• f(x, y) = x - y

• f(x, y) = x + y

• f(x, y) = x^2 - y^2

How can you reset the app to its original state?

• By pressing the double arrows

• By clicking the reset button

• By closing and reopening the app

• By refreshing the browser

What feature allows you to manually adjust the axes?

• Reset button

• Manual axis adjustment

• 3D goggles button

• Zoom buttons
