Instructions

Select a graph from the above list
Edit the definition of the graph and press the Draw Graph button
You can copy and paste text from different graph definitions
When you have the graph you want, paste the text into your Powerpoint™ slide
Grab a picture of the graph and paste that into your slide where the graph should appear.

Graph of points

Vertical line graph

Use the function keyword to graph a vertical line (even though it's not a function.)
Use additional function statements to add more functions to the graph if you want
The window keyword sets the graph window
Separate each field following the window keyword with a colon(:)
The grid=no field turns off the grid
You can add a slider to make the vertical line interactive.

Linear Inequality graph

Linear Function graph

Interactive Parallel Lines

Use more than one function statement to graph multiple functions
The position field defines the position of the second function relative to the top right corner
Variables a and b are replaced by slider values
Precede each variable with %
Use the slider keyword to define a slider for each variable
You can override defaults for the min, max and initial value of each slider

Interactive square root functions

Two function statements graphs two functions
The position field defines the position of the second function relative to the top right corner
Variables h and k are replaced by slider values
Precede each variable with %
Use the slider keyword to define a slider for each variable
You can override defaults for the min, max and initial value and step of each slider

Quadratic Inequalities

Two function statements graph two inequalities
Use <= for ≤
Use >= for ≥
The position field defines the position of each inequality relative to the top left corner

Dynamic Quadratic Function

Use the function keyword to graph any function
Variables h and k are replaced by slider values
Precede each variable with %
Use the slider keyword to define a slider for each variable
You can override defaults for the min, max and initial value and step of each slider
The dynamic keyword in the function definition replaces the variables with numbers in the equation

Rational Inequality

Use the function keyword to graph an inequality
Use <= for ≤
Use >= for ≥
Use the position field to define the position of each inequality relative to the top left corner
Use the grid=none field to turn off the grid
Use the scale=none field to turn off the scale (You may need to do this for small graphs.)

Interactive Rational Equation

Use the function keyword to graph any function
Variables a and k are replaced by slider values
Precede each variable with %
Use the slider keyword to define a slider for each variable
You can override defaults for the min, max and initial value and step of each slider
Use the window statement to override the default window. Separate each field with a colon (:)

Polynomial Function

Use the function keyword to graph any function
The positionf ield tells where to display the equation relative to the top left corner
The window statement overrides the default window
Separate each field with a colon(:)

Absolute value Function

Two function statements display two functions
The position = none field says not to display the function
Variables h and k are replaced by slider values
Precede each variable with %
Use the slider keyword to define a slider for each variable
You can override defaults for the min, max and initial value and step of each slider

Step Functions

Trig Functions

Trig functions include sin, cos, tan, asin, acos, atan
Use scale=pi in the window statement and the slider statement to show the scale in pi units.
The labels field overrides the default labels for the axes
If possible avoid using slider variable a in front of sin because this is interpreted as the asin function
If you really need to do the above, use the eval and latex fields in the function definition (see syntax guide.)

Exponential Function

No Equation Shown

For static graphs, use position = none field to turn off the display of the function
You may want to do this and display the function outside the graph using MathType

Empty Graph

Empty Graph

Empty Graph

You can also display a coordinate system with no graph for the on screen teacher to use.

Normal Distribution

Here is an example of a common graph whose function definition is not currently supported by the parser
However, the eval and latex fields define overrides so the function is evaluated and displayed correctly
