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
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 on Coolmath 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 |
