- Low end of the domain: 0
- High end of the domain: 423
- The function f(x): -0.00504238 * x^2 + 2.34528 * x - 69.4962
The following three brief documents explain how this module was created.
- One-sheet instructions on adding a curve in Image_and_Cursor.
- One-sheet instructions on using forms.
- One-sheet instructions on creating a new HTML page on the fly responding to the user.
Complete documentation for the Image_and_Cursor applet is contained in the User's Manual. This applet is very flexible. Included among its features are controls for:
- Appearance of the applet, including the colors of all the displayed elements and their placement
- The initial position of the cross hairs
- Which elements are displayed
- What marks are used when the user marks a point and whether the marks are connected by line segments
- Whether to add a curve to the image in any of the forms y = f(x), x = x(t) and y = y(t), and r = f(theta), with further controls for the number of segments used to draw the curve, the domain of the independent variable, and the color and thickness of the curve
- Choice of listed output in any one of three different formats for use in a spreadsheet, Maple, or Mathematica
- Choice of whether to produce polar coordinates as well as Cartesian coordinates for marked points
- Location of the origin for polar coordinates (if used)
Because most parameters have the most commonly used options set as default values, most curriculum developers will need to specify only a few parameters. For complete documentation see the User's Manual.
We continue in the next section with another module that uses this applet to study the shell of a chambered nautilus.
