Function curve

Parent Previous Next

The function curve is not an object.

MathGraph32 draws a function curve as a point locus.

Your figure must own a frame.

You must first create a function must be created through icon .

If your figure contains one or several frames, at the bottom of the dialog box the checkbox Draw curve is selected.

If you keep the checkbox Draw curve selected, the function curve will be added to your figure (defined on R).

If you wish to draw this function curve only on an interval (or don't want the curve to be created) uncheck Draw curve checkbox.


If you have chosen not to check Draw curve checkbox, you can draw the curve afterwards using icon .

A dialog box pops up.

Select the function and the frame the curve will be traced in.

Select the type of interval on which the curve is to be calculated.


The function curve is created as follows :


MathGraph32 creates a point linked to a line, ray or segment according to the type of interval chosen.

Then are created :


In the dialog box you can change the number of points used to draw the point locus (curve).


You can also ask for :


Three more tools allow function curves creation.


Tool  allows the creation of a function curve with one or two brackets at the edge of the curve.


Tool allow the creation of a curve going through n given points and the tangent slope at these points. (n in the range 2 to 10).


Tool  allows the creation of a polynomial function curve (of degree less or equal n) going through n given points (n valant de 2 à 8).


To be noticed : A function curve is a point locus and therefore you can create a point linked to it.
