New in FX Graph 4.00 (Dec 21, 2010)

  • 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;
