FNGraph

Graphing and analyzing mathematical functionsCustomization of graphs and coordinates system appearance. Support for Complex syntax, large variety of functions, user-defined variables. Tools for function evaluation, Analysis and integration.Customize each graph`s properties: the Function and the Description, the Min and Max values of the drawing interval, the Precision of representation, the Max gap Between two consecutive points to be marked as discontinuance. A graph can be drawn with lines or points of different sizesYou can evaluate any function at any point. The evaluation engine supports a large set of operators, functions and constants. For ease of use it also understands other variants of functions naming (aliases, for example: Inverse Tangent - atn, arctan, arctg, atan).Trace a graph to see how it progresses. You can see the coordinates of the current point in the Values Frame.Analyze a function to find it`s zeroes. The results can be copied to the clipboard along with analysis parameters or you can copy just the selected values. The precision can be defined numerically or in steps.Calculate the definite integral or find the area between the graph and the X axis. Set the integration interval and the precision, which can be defined numerically or in steps.
