This is a scientific calculator program with many extensions. Along with the usual calculations that scientific calculators perform the RSC will calculate: the definite integral of a function, solve equations and absolute extrema searching. The RSC also has functions for statistics, in the memory, as well as some special functions (e.g. Gamma, Bessel,...) and common functions (i.e. ln, exp., cos,...). The help screens are very useful and a mouse can be utilized in all calculations.
