Math software for students studying precalculus and calculus. Can be enteresting for teachers teaching calculus.Math Center Level 2 consists of scientific Calculator, Graphing calculator 2D Numeric, Graphing calculator 2D Parametric, and Graphing calculator 2D Polar.

Scientific calculator works in scientific mode. All numbers in internal calculations are treated in scientific format, like 1.23456789012345E+2 for 123.456789012345. You also can use scientific notation in formulas. If you get result NaN, like in ln(-1), that means that the function is not defined for given argument. Otherwise scientific calculator is similar to Simple Calculators. There are options to save and print calculation history, to change font, and standard editing options.

Graphing calculator 2D Numeric is a further development of Graphing Calculator2D from Math Center Level 1. It has extended functionality: hyperbolic functions are added. There are also added new capabilities which allow calculating series, product series, Permutations, Combinations, Newton Binomial Coefficients, and Gauss Binomial Coefficients . Graphing calculator 2D Numeric has capability to build graphs for first and second derivatives, definite integral (area under curve) and length integral (length of curve). Since these calculations are done numerically, not symbolically, the calculator is called Numeric.

Graphing calculator 2D Parametric is a generalization of Graphing calculator 2D Numeric. Now x and y are functions on parameter �?. If you are typing formula using keyboard, then you can use "tau" for �? . Since all calculations are done twice, for x and y, there was some sacrificing of precision in order to keep speed of calculations. So, although it is possible to build the same graph of y=f(x) in parametric calculator using x=�?, y=f(�?), the Graphing calculator 2D Numeric will build it with greater precision.

Graphing calculator 2D Polar is a specialization of Graphing calculator 2D Numeric.

Source Code Scanners is the high performance library of visual components for C++ Builder and Delphi intended for creating analyzers and parsers of source codes.

It includes components of the lexical analyzers: C++, Object Pascal (Delphi), PHP, HTML, CSS1 and the C++ preprocessor, but also contains the full set of base classes, which provides a possibility to create lexers and parsers of any other languages.

These components may be used to build applications, which require the source code analyzing (tools of helps creating; calculators of expessions; designers of source codes; interpreters and compilers and etc.).

The lexical analyzers uses DFAs (Deterministic Finite Automata) to match tokens found on the character input stream. DFAs are defined by the set of regular expressions in a source code and are created at runtime. More than one automaton (lexical class, lexical tree) may be defined. Actions attached to regular expressions (which are executed when that expression has been matched on the input stream) may switch from one lexical class to another. The TLexTree class maintains converting a set of regular expressions into the DFA array.

Source Code Scanners provides also classes, which support a work with command-line options, calculating of constant expressions and etc.

The full source code of Source Code Scanners is available in Professional edition.
