FX Graph is really easy to use - it is dead simple. So simple that secondary students will be using it to solve problems within minutes of first seeing it.

• Teachers only - email your address for free Trial CD of FX MathPack or download it.
• Download evaluation version of FX Graph 3 (5.4 mb)
• Read the FX Graph 3 manual online (1.8 mb)

As a quick example, think how long it would take you to draw this graph, with the annotations, in your current graphing package. In FX Graph 3 it takes seconds. FX Graph finds all the points of interest and displays them automatically as you move your mouse around the screen. One click and the annotation is added to the graph.

Does simplicity limit versatility? Not with FX Graph 3. FX Graph has a large number of capabilities - far more than we can show you here.

• FX Graph makes setting axes about as easy as it can be - it can even be totally automatic. Axes that would take minutes to create with other graphing packages can be created in seconds.
• FX Graph uses Efofex's equation technology. Equations are entered as the student sees them. There are very few "tricks" to learn.
• Finding Points of Interest (maxima, minima, intercepts, asymptotes, point discontinuities, points of intersection, points of inflection) is easy. FX Graph automatically calculates all points of interest and displays them when the mouse is close. There is nothing to learn - just move the mouse.
• Annotating graphs - adding labels to important points is easy. FX Graph allows you to add comprehensive annotations to graphs with a simple click. When FX Graph AUTOMATICALLY displays an important point, ONE CLICK will turn it into a permanent annotation.
• FX Graph will let you draw graphs exactly the way you want them. Our international focus means that just about every option is available.
• FX Graph is designed to be simple to use with a very small learning curve. Thirteen year old, average students will be using it to graph functions in minutes. Eighteen year old, talented students will not find it limiting.
