Click on Draw Tangent Line, then click on a point on the curve. This forces the [Curve Fit] button to use a straight line to fit the points.
Before copying, you might want to resize the Graphmatica window, as resizing in a word-processor might make the picture ugly. You can plot data points and ask Graphmatica to find the best-fit-line. Click on the graph of the derivative to see it’s formula at the bottom. Then you can paste it into a document.

For the parabola, this also finds the vertex. Here is a summary of common symbols. It works well for IB Math Portfolio work.
This will squash your graph to make room for the data table. You can also graph a line from an equation, without solving for y.

Below is a quick-start introduction to Graphmatica. You can label points or add other annotations notes to your graph. 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.
The equation of th best-fit-line appears at the bottom of the screen. When you start Graphmatica the first time, you might not like the layout – funny colors, small numbers. If you don’t want to see the graph, hide it.

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 titorial will have white paper with colored lines, and you can draw your first graph. After typing the points, you can hide the data-table again but the dots will stay.
There are two ways to zoom in and out: Right-click on the graph then choose: Type the coordinates of the points you want to mark with dots. The pictures are smaller than you will normally see. Graphmatica draws mathematical graphs, like: This gives better results than tracing, as tracing only finds approximate graphamtica – e. Graphmatica will also graph relations implicit functionssuch as circles and conic sections.
In the formula-box, type: If you drew lots of graphs and erased them, they will all appear again when you open the file next time. Click on the curve you want to investigate. You can also graph inequalities and it will shade in areas for you.
There are two ways to erase a graph.
