Here is a brief overview of what Xcas is able to do: [9] [10] Xcas has the ability of a scientific calculator that provides show input and writes pretty print; Xcas works also as a spreadsheet; [11]
These are functions obtained by composing exponentials, logarithms, radicals, trigonometric functions, and the four arithmetic operations (+ − × ÷). Laplace solved this problem for the case of rational functions , as he showed that the indefinite integral of a rational function is a rational function and a finite number of constant ...
The group operation is the composition of functions (performing one rearrangement after the other), which results in another function (rearrangement). The properties of permutations do not depend on the nature of the elements being permuted, only on their number, so one often considers the standard set S = { 1 , 2 , … , n } {\displaystyle S ...

Lottery mathematics is used to calculate probabilities of winning or losing a lottery game. It is based primarily on combinatorics, particularly the twelvefold way and combinations without replacement. It can also be used to analyze coincidences that happen in lottery drawings, such as repeated numbers appearing across different draws. [1
Removed functions include last answer recall, nPr/nCr, reduction study, highest common factor/lowest common multiple, quotient/remainder calculation, equation playback. However, it gains cubic power/root, hyperbolic trigonometry, angle unit conversion, polar/cartesian coordinate conversion, complex number calculation, Bin/Oct/Hex calculations ...

The first American-made pocket-sized calculator, the Bowmar 901B (popularly termed The Bowmar Brain), measuring 5.2 by 3.0 by 1.5 inches (132 mm × 76 mm × 38 mm), came out in the Autumn of 1971, with four functions and an eight-digit red LED display, for US$240, while in August 1972 the four-function Sinclair Executive became the first ...
