FX Graph software was created to be a simple, easy to use, but powerful, graphing program. Most graphing packages offer powerful features but they are difficult to learn, difficult to teach and difficult to use. Many schools spend more time teaching students how to use the program rather than actually using it. FX Graph is different - it is dead simple. So simple that secondary students will be using it to solve problems within minutes of first seeing it. It is designed to be used, with minimal training, by twelve and thirteen year old students but is powerful enough to support the graphing needs of all secondary school students.

Key Features:
· Graph Cartesian, inverse, conic, implicitly defined, polar and parametric relationships.
· Analyse most functions and provide information on important points automatically.
· Plot points, groups of points and vectors.
· Graph on equal aspect and fixed scale axes
· Automatically detect asymptotes and point discontinuities in rational functions.
· Show tangent lines and 1st and 2nd derivative curves.
· Calculate and display definite integrals including areas to the y axis.
· Zoom and graph on broken axes.
· Easily annotate your graph using automatically generated text.
· Graph inequations and the feasible region for a system of inequations.
· Include constants in functions - interactive animations
· Produce publication quality graphics with a minimum of effort.

What's New in FX Graph 4?
Here is a small selection of the capabilities of FX Graph 4

- Integral Approximations
Integrals can now be calculated using approximations such as the trapezium rule.

- Tables of Values
Tables of values can be calculated and displayed for most function types. The values in the table can be quickly copied to the clipboard for use in other products.

- Complex Numbers
FX Graph 4 can interpret and display complex numbers and equations. This graph was entered as z5 = 32+128i.

- Greatest Integer and Sign Functions
Drawn the way they should be.

- Piecewise Defined Functions
Automatically found and drawn the way they should be.

- Slope/Direction Fields
and solutions of 1st order differential equations

- Transparency on Families of Curves
Families of curves are much more useful when combined with transparency effects.

- But That's Not All
FX Graph 4 contains hundreds of other new features like: easy translation; showing derivatives without the function curve; showing secant lines; marked points; higher quality graphics including transparency; better feasible regions;
