3D Point Plotting Concepts

This video tutorial demonstrates how to plot points in three dimensions using a JavaScript app from the Exploring Multivariable Calculus site. It covers setting up the plotter, plotting points with different colors and sizes, adjusting the view for better visibility, and saving the final plot as an image.

What is the primary tool used for plotting points in 3D in this tutorial?

• Python Matplotlib

• Google Sheets

• Microsoft Excel

• 3D Cal plotter JavaScript app

What is the first step to take when the app is opened?

• Plot the default surface

• Clear the default plot

• Change the color of the plot

• Enter the first point

How can you adjust the view to better see the plotted point?

• By zooming in or out

• By rotating the view

• By entering a new point

• By changing the color

What color is used to plot the first point (3, 4, 0)?

• Black

• Blue

• Green

• Red

What is the Z-coordinate of the first point plotted?

• 5

• 0

• 4

• 3

Which point is plotted in red?

• (3, 4, 0)

• (3, 4, 5)

• (-4, 3, 4)

• (-5, -2, -3)

What is the significance of the Z-coordinate in determining the position of a point?

• It is irrelevant in 3D plotting

• It shows the height above the XY plane

• It indicates the size of the point

• It determines the color of the point

Which color is used to plot the point (-5, -2, -3)?

• Red

• Purple

• Green

• Blue

What is the final step to save the plotted graph as an image?

• Click the graph button

• Select save as PDF

• Select save the plot as a PNG

• Print the screen

What is the color of the last point plotted in the tutorial?

• Black

• Purple

• Red

• Green
