Graphmatica draws mathematical graphs, like: It works well for IB Math Portfolio work.
Below is a quick-start introduction to Graphmatica. The pictures are smaller than you will normally see. When you start Graphmatica the first time, you might not like the layout – funny colors, small numbers. Now you will have white paper with colored lines, and you can draw your first graph. In the formula-box, type: Either change the colors of Graph1, Graph2, etc all to black, or change to Monochrome layout.
There are two ways to zoom in and out: This gives better results than tracing, as tracing only finds tutotial coordinates – e.
Type the coordinates of the points you want to mark with dots. This will squash your graph to make room for the data table.

After typing the points, you can hide the data-table again but the dots will stay. You can label points or add other annotations notes to your graph.
tutlrial 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. You can plot data points and ask Graphmatica to find the best-fit-line.
This forces the [Curve Fit] button to use a straight line to fit the points. The equation of th best-fit-line appears at the bottom of the screen.
Graphmatica will also graph relations implicit functionssuch as circles and conic sections. You can also graph a line from an equation, without solving for y. You can also graph inequalities and it will shade in areas for you. Then you can paste it into a document. Before copying, you might want to resize the Graphmatica window, as resizing in a word-processor might make the picture ugly.
If you drew lots of graphs and erased them, they will all appear again when you open the fraphmatica next time.
There are two ways to erase a graph. Right-click on the graph then choose: You must use Graphmatica notation to define functions, but do not use this notation when writing mathematics in an IB Portfolio. Here is a summary of common symbols.

Click on the curve you want to investigate. For the parabola, this also finds the vertex. Click on Draw Tangent Line, then click on a point on the curve. If you don’t want to see the graph, hide it. Click on the graph of the derivative to see it’s formula at the bottom.
