For the parabola, this also finds the vertex. You can label points or add other annotations notes to your graph.
Graphmatica Help – Introduction to Graphmatica
Graphmatica tutogial mathematical graphs, like: This gives better results than tracing, as tracing only finds approximate coordinates – e. This will squash your graph to make room for the data table. There are two ways to erase a graph. This forces the [Curve Fit] button to use a straight line to fit the points.
Below is a grapmatica introduction to Graphmatica. The equation of th best-fit-line appears at the bottom of the screen. Here is a summary of common symbols.
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. Now you will have white paper with colored lines, and you can draw your first graph. If you drew lots of graphs and erased them, they will all appear again when you open the file next time.
Right-click on the graph then choose: The pictures are smaller than you will normally see. You can also graph inequalities and it will shade in areas for you.
Either change the colors of Graph1, Graph2, etc all to black, or change to Monochrome layout. You must use Graphmatica notation to define functions, but do not use this notation when writing mathematics in an IB Portfolio. 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. Click on Draw Tangent Line, then click on a point on the curve.

It works well for IB Math Portfolio work. If you don’t want to see the graph, hide it.
There are two ways to zoom in and out: Click on the graph of the derivative to see it’s formula at tuutorial bottom. In the formula-box, type: You can plot data points and ask Graphmatica to find the best-fit-line.
After typing the points, you can hide the data-table again but the dots will stay.
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. Graphmatica will also graph relations implicit functionssuch as circles and tytorial sections.
Type the coordinates of the points you want to mark with dots. You can also graph a line from an grapumatica, without solving for y.
