There are two ways to zoom in and out: Click on Draw Tangent Line, then click on a point on the curve. Graphmatica draws mathematical graphs, like: It works hraphmatica for IB Math Portfolio work.

You can also graph a line from an equation, without solving for y. The pictures are smaller than you will normally see. Graphmatica grahmatica also graph relations implicit functionssuch as circles and conic sections.

This will squash your graph to make room for the data table. Either change the colors of Graph1, Graph2, etc all to graphmaticaa, 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.

Now you 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 tutoorial will stay. When you start Graphmatica the first time, you might not like the layout – funny colors, small numbers.

Type the coordinates of the points you want to mark with dots. This forces the [Curve Fit] button to use a straight ttutorial to fit the points. If you don’t want to see the graph, hide it.

Right-click on the graph then choose: For the parabola, this also finds the vertex. You can label points or add other annotations notes to your graph. There are two ways to erase a graph. Then you can paste it into a document.

The equation of th best-fit-line appears at the bottom of the screen. Below is a quick-start introduction to Graphmatica.

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. Click on the graph of the derivative to see it’s formula at the bottom. 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 file next time. You can plot data points and ask Graphmatica to find the best-fit-line.

Here is a summary of common symbols.

In the formula-box, type: Click on the curve you want to investigate. This gives better results than tracing, as tracing only finds approximate coordinates – e. You can also graph inequalities and it will shade in areas for you.
