Guidelines to use the calculator
1. No slashes, but decimals are OK
2. Do not enter units such as cm, inch, m, ft, etc...just enter the numbers only.

(x1, y1) = (17 cm, 12 cm)
(x1, y1) = (9 cm, 6 cm)
Enter 17 in the box that say x1
Enter 12 in the box that say y1
Enter 9 in the box that say x2
Enter 6 in the box that say y2
After you hit calculate, you should get 10 as an answer
The answer is then 10 cm

x1:                         x2:

y1:                         y2:

OPEN & RUN the Ultimate FREE 2 and 3-D graphing calculator brought to you by GraphCalc

The GraphApplet 1.0 is a full featured Graphing Calculator with some rare features added.

It is recommended that you use Netscape 4.x or higher or IE 4.x or higher for this applet and
at least 800x600 resolution with more than 256 colors. Result in older browsers and with different
resolution or color depth may vary, some problems have been noticed in older browsers.

The GraphApplet has all the common operators and functions as expected from any scientific
calculator and combines it with function graphing capabilities.

The GraphApplet supports juxtaposition which means you can write your expressions just as you
would write them on a piece of paper, for example xcos(x) or 5x^3-6x

The GraphApplet has support for symbolic differentiation using the diff function.

To use the applet as a calculator click on the buttons or use the keyboard to form your expression
and then press enter or click the Eval button to evaluate.
Note that when you click on a function button it will fill in a left parenthesis, you will have to match it
with a right parenthesis either by clicking on the ) button or enter it with the keyboard.

To draw a function enter the function by clicking on the buttons or enter them with the keyboard
and then press the PlotF button, you can only draw function of type y=f(x) .
To zoom into an area, select an area with the mouse ( click, hold down and drag ) and release,
the area you selected will be zoomed in, to zoom out use the ZOut button.
To reset the bounds to the original x:[-10,10] y:[-10,10] click on the Reset button.

To clear the input field click the Clear button, to clear a individual drawed function double click on the
function name in the list to the right of the applet or click on the Cls button to clear the whole screen.

To enter something into memory first click the M-> button and click on either m1 or m2,
to clear the memory first click on MCls and then either m1 or m2

All Functions

 Eval Evaluates an expression, the calculator first tries to evaluate the expression, if it fails then it tries to draw the expression. Clear Clears the input area. PlotF Plots a function of type y=f(x) ZOut Zooms out the current area with a factor of x2. ( to Zoom into an area, select the area with the mouse and release. ) Reset Reset the bounds to the original x:[-10,10] y:[-10,10] Cls Clears the whole drawing area and all functions. ( to clear a individual function double click on the function in the list to the right of the applet. ) M-> Enters an expression or a value into memory, first click this button and then chose either m1 or m2 MCls Clears the memory, first click this button and then on either m1 or m2 to clear that memory. ( note that memory will be gone if you leave the page with the applet and then return at a later point. ) m1 Memory 1 m2 Memory 2

 These operators can be entered either with the buttons on the calculator or through the keyboard.
