Description
The GraphApplet 1.0 is a full featured Graphing Calculator with some rare features added. This offers most of the features offered by handheld graphing calculators.
The GraphApplet graphing calculator has all the common operators and functions as expected from typical scientific calculators and graphing calculators for graphing functions.
The GraphApplet, like other graphing calculators, 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 graph 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 graph function of type y=f(x) .  To zoom into an area of the graph, 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 of the graph 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 graphed 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

Hit the Eval button to graph!


All Functions of Coolmath's Graphing Calculator

Eval  Our graphing calculator evaluates an expression, the calculator first tries to evaluate the expression,
if it fails then it tries to draw the expression.
Clear Our graphing calculator clears the input area.
PlotF Our graphing calculator plots a function of type y=f(x)
ZOut Our graphing calculator zooms out the current area with a factor of x2.
( to Zoom into an area, select the area with the mouse and release. )
Reset Our graphing calculator reset the bounds to the original x:[-10,10] y:[-10,10]
Cls  Our graphing calculator 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-> Our graphing calculator enters an expression or a value into memory, first click this button and then chose either m1 or m2
MCls Our graphing calculator 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

Note that some of these commands are different than those on typical graphing calculators.

These operators can be entered either with the buttons on the calculator or through the keyboard. 
sqrt  sqrt of a value or expression.
sin sin of a value or expression.
cos cos of a value or expression.
tan tan of a value or expression.
atan atan of a value or expression.
acos acos of a value or expression.
asin asin of a value or expression.
acotan acotan of a value or expression.
exp exp of a value or expression.
ln ln of a value or expression.
10log The 10 logarithm of a value or expression.
fac The faculty of a value or expression.
diff Symbolically differentiates an expression of one variable.
pi The constant PI
euler The Euler constant, base for the natural logarithm.
+ Addition
- Subtraction.
* Multiplication.
/ Division.
^  "Power to" operator 

 
These additional operators can be entered only through the keyboard. 
sinh Hyperbolic sine
cosh Hyperbolic cosine
tanh Hyperbolic tangens
abs Absolute value of value or expression.
ceil Returns the smallest (closest to negative infinity) value that is not less than the argument and is equal to a mathematical integer.
floor Returns the largest (closest to positive infinity) value that is not greater than the
argument and is equal to a mathematical integer.
sfac Semifaculty of value or expression.
round Rounds the argument to the closest mathematical integer. Example: round( 3.4 ) = 3.0, round( 4.99 ) = 5.0 etc...
fpart Returns the decimalvalue of its argument
[base]log(...) Any logaritm.  Example: 10log(10) = 1.0, exp(1)log(exp(1)) = 1.0
% Modulo
== Equal, returns 1.0 if it's arguments are equal or 0.0 othervise.
!= Not Equal, returns 1.0 if it's arguments are not equal or 0.0 othervise.
&& And, returns 1.0 if both arguments evaluates to 1.0, or 0.0 othervise.
|| Or, returns 1.0 if any of it's arguments evaluates to 1.0, or 0.0 othervise.
> Larger than, returns 1.0 if the value of the argument to the left is larger than the value of the argument to the right, or 0.0 othervise.
< Less than, returns 1.0 if the value of the argument to the left is less than the value of the argument to the right, or 0.0 othervise.
>= Larger than or equal to, returns 1.0 if the value of the argument to the left is larger
than or equal to the value of the argument to the right, or 0.0 othervise.
<= Less than or equal to, returns 1.0 if the value of the argument to the left is less than or equal to the value of the argument to the right, or 0.0 othervise.
! Not, returns 0.0 if it's argument evaluates to 1.0 and returns 1.0 if it's argument evaluates to anything other than 1.0
