Enter two complex numbers (z and c) as ordered pairs of real numbers, then click a button to iterate step by step. The iterates are graphed in the x-y plane and printed out in table form. This is an introduction to the idea of prisoners/escapees in iterated functions and the calculation of fractal Julia sets.
Introduces students to the vertical line test for graphs of functions.
Two Variable Functions (Discussion)
Introduces 2 variable functions as ordered pairs and how to operate perform operations on ordered pairs.
Teaches distinguishing between possible and impossible graphs of functions as well as causes of graphical impossibility.
Sample figure drawn on a coordinate grid for use with Ordered Simple Plot Activity (http://www.shodor.org/interactivate/activities/OrderedSimplePlot/).
This worksheet is for use with the General Coordinates Game activity (http://www.shodor.org/interactivate/activities/GeneralCoordinates/).
This worksheet is for use with the activity Coloring Remainders in Pascal's Triangle (http://www.shodor.org/interactivate/activities/ColoringRemainder/).
This worksheet is for use with the lesson InteGreat (http://www.shodor.org/interactivate/lessons/InteGreat/).
Introduces students to concepts of transformations.
Polar Coordinates (Activity)
This activity allows the user to explore the polar coordinate system. The applet is similar to GraphIt, but instead allows users to explore the representation of a function in the polar coordinate system.
