What these look like

How point by point function drawing looks

Lots of points, one point at a time

Probably the easiest way to draw a function with EZ Math Movie is to plot dozens of points on the function, and space these points close together so that the shape of the function becomes clear. That will be our approach in this tutorial example. Here are our steps:

The example program

Angle measurement: Degrees Radians

Go on input

Change the value of deltaX and see how the number of points changes. An example:

deltaX = 1;  // few points
deltaX = 0.1 // many points

Change the values for the slope, m, and the y-intercept, b, and see how the line changes. For example:

m = -2;
b = -5;

Another experiment

Try graphing a parabola.
