Description of the http://coolmath.com graphing calculator(above).
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
expression, the calculator first tries to evaluate the expression,
if it fails then it tries to draw the expression.
