Here is a summary of common symbols.

Type the coordinates of the points you want to mark with dots. If you want to move the annotation later, double-click on it, click the [Place] button, then click on the graph to place that annotation.
Graphmatica Help – Introduction to Graphmatica
Now you will have white paper with colored lines, and you can draw your first graph. If you don’t want to see the graph, hide it. You must use Graphmatica notation to define functions, but do not use this notation when writing mathematics in an IB Portfolio. For the parabola, this also finds the vertex. Click on the graph of the derivative to see it’s formula at the bottom.

In the formula-box, type: You can also graph a line from an equation, without solving for y. Graphmatica draws mathematical graphs, like: It works well for IB Math Portfolio work. There are two ways to zoom in and out: Then you can paste it into a document.

You can plot data points and ask Graphmatica to find the best-fit-line. You can also graph inequalities and it will shade in areas for you. After typing the graphmatics, you can hide the data-table again but the dots will stay. This forces the [Curve Fit] button to use a straight line to fit the points.
You can label points or add other annotations notes to your graph. There are two ways to erase a graph.
The equation of th best-fit-line appears tutoriao the bottom of the screen. Click on Draw Tangent Line, then click on a point on the curve. If you drew lots of graphs and erased them, they will all appear again when you open the file next time. When you start Graphmatica the first time, you might not like the layout – funny colors, small numbers.
Click on the curve you want to investigate.
This will squash your graph to make room for the data table. Right-click on the graph then choose: This gives better results than tracing, as tracing only finds approximate coordinates – e. Graphmatica will also graph relations implicit functionssuch as circles and conic sections.

Before copying, you might want to resize the Graphmatica window, as resizing in a word-processor might make the picture ugly. Either change the colors of Graph1, Graph2, etc all to black, or change grpahmatica Monochrome layout. The pictures are smaller than you will normally see.

Below is a quick-start introduction to Graphmatica.
