Math 115  Lab #1
M. Flashman

Initial examples for experience:
Steve Simonds :  instructional videos.
• Video 1 – Getting started [3:46]

• Plotting the line y = 2+ 1.
• Using the slider (like the TRACE function on TI calculators).
• Creating a table of points.

• Changing the background color.
• Changing the width and color of your function.
• Adding a grid to your graph.
• Showing your equation on your graph.
• Changing fonts.

• Video 3 – The Viewing Window [4:50]
• Using the keypad to move around the plane.
• Specifying the corner points in the graph window.
• Specifying the center and width of the graph window.
• Other ways to change the graph window.

• Equa Menu : Further explorations.
• Plot a function :explicit... y = f (x)...
• f(x) = 2x-4
• f(x) = x^2 - 4   (Zeroes on One Menu)
• f(x) = x^3 - 2

• Plot a point : Point...
• (1,3)
• (a,b)    Animation
• (a, a^2), (a, f(a))
• Plot a line:

• aX + bY = c  ;
For a vertical line a=1, b=0, c=?

• library: for reference.
• The Inventory : Inventory... Ctrl  I
• Table
• Params
• family

• One Function Menu: Further explorations.
• Slider...
• function choice
• the "slider" [used for tracing and finding values of f(x).]
• mark point- added to inventory!

• Video 4 – Finding points of interest and creating new functions from old   [10:38]
• Finding zeros of the function .
• Finding Xtreme value points on the function .
• Finding points of intersection between the functions and .
• Zeros...   Save as...
• Extremes... Save as...
