Download -- Instructions

Download -- General Instructions:

These applications were tested only on the Linux Operating System environment. Hence every instruction here refer to Linux OS.

With the "shift" key pressed, click on the program you want to download. To uncompress the file use the command "tar xvfz fileName.tgz." This create a directory named "fileName". In order to embed the applet on your Web page, I assume that your page and the fileName directory are in the same directory.

Sketch a graph:

Description: in this Java applet, you may plot a few points P(x, f(x)) and see how the graph looks like.

Instructions:

Click on the applet to get Started.
Enter values for x and y in the corresponding columns.
Hit y = f(x), if you want to set y as a function of x. This will work only if you are prompted on the y-column.Here, I list some examples on how you should enter f(x):
- - f(x) = x^2; will evaluate x^2 on the line you are prompted.
- - f(x) = 3 * x + sqrt(x) | 1-10; evaluate 3 * x + sqrt(x) on lines 1 through 10.
- - f(x) = ln(x) |1,3,7-10; sin(x^2),2; cot(x); evaluates ln(x) on lines 1, 3, 7 through 10, sin(x^2) on line 2, and cot(x) on the lines left.
Hit graph to see the points (x,y) on an xy-plane. Link the points to have an sketch of the graph of f(x) if the domain(f) were [smallest x-value, greatest x-value]. If you want to clear x & y column, hit edit & ?.

Linear Function with parameters a & b:

Description: this applet illustrates how a linear function graph varies as you change the values of a and/or b.

Instructions:

Drag the pointer over ( )Change the slope or ( )Change y-intercept, and choose the feature you want to change by clicking the mouse button-1.
If you choose to change the slope (ie; a), point the mouse at the tip of the blue arrow, press button-1 and rotate the line. Simultaneously, you'll see the value of a varying.
If you choose to change the y-intercept (ie; b), point the mouse at the center of the blue circle, press button-1 and drag the line up/down. Simultaneously, you'll see the value of b varying.

Graph a polynomial function with at most 10 parameters

Description: this applet illustrates how a polynomial function graph behaves as coeffiecients values are changed.

Instructions: In this applet, you may change parameters A_i, x-range, y-range, and replot. You may also reproduce a "boxed" a region: place the cursor at the left top corner and press mouse-button-1; with the button pressed, drag the pointer until you reach the right bottom corner; release and see the new graph.
