The following functions can be used:
Function names must be written in lower case only.
The 'if' function can be used to glue different functions together, e.g.: if( x<0,x,sin(x)) . This describes the following contiguos function:
The following predefined variables may be used
x is the predefined loop variable which varies during a function plot.
Variables and expressions may both be used in the function definition and in the various parameters of the program, like e.g. the Dimension Setup (the dialog which defines the size and location of the area where the function is drawn);
See the following example for the use of variables:
| EVAL | Evaluates the Function as mathematical expression. Can be used for simple calculations |
| DRAW | Draws the function defined by the expression as a function in 'x' |
| ZOOM | Zooms out by multiplying the upper, lower, left and right borders by 1.5; the y-scale is adapted to 1/10th of the distance between the upper and lower border; the x-scale remains unchanged. |
| AUTO | Calculates the best value for upper and lower border, so that all function values are in the visible range and draws the function again |
When the function drawing is complete, you can measure the function
with the pen by tapping to the screen - the (x,y) coordinates of the point you
pointed on will appear in the upper left corner of the screen. This my partly
overwrite the function - if you want to restore the full function drawing again,
simply press DRAW.
The clipboard may be used to store and retrieve functions from the memopad or similar applications. Currently MathPlot does not have an own database - this feature is scheduled for the next version.
