57 Pi: (Mathematica) Documentation (57.html)

To type a named character into m:

Type \[AHat] for a circumflex
As soon as you type the final "]", the Named Character will be converted to its Wolfram Equivalent
eg \[ImaginaryI] will become i in italics.
eg \[lambda] will become the greek letter lambda

2. To look up a special character, use NetSurf in ubuntu and Edit->Find the string eg "imaginary"
in List of Named Characters

3. Greek alphabet:

alpha	eta	nu	tau
beta	theta	xi	upsilon
gamma	iota	omicron	phi
delta	kappa	pi	chi
epsilon	lambda	rho	psi
zeta	mu	sigma	omega

<--Back Examples

1. To Display a red disk:
Graphics[List[RGBColor[1, 0, 0],Disk[List[0, 0]]]]
2. Number formats:
Map[FullForm,{123,1/23,1.23,1+23\[ImaginaryI]}]
...produces {123,Rational[1,23],1.23`,Complex[1+23\[ImaginaryI]}
3. FullForm shows how to type an m expression on a keyboard:
FullForm[{\[AHat], 123, 1/23, 1.23, 1 + 23\[ImaginaryI]}]
...produces List[\[AHat], 123, Rational[1,23], 1.23`,Complex[1, 23]]

<--Back m Usage Notes

To execute an expression, hit shift-Enter
For calculations use Wolfram
A Mathematica program is a Notebook
Mathematica and Wolfram are free in Raspberry Pi OS
.asp and java do not work in WebSurf

<--Back Evolution

mathematica (m) was created ( by Stephen Wolfram ) and released in June 23, 1988. A major version is "mathematica 9" which was released on November 28, 2012. In Dec 14,2022, mathematica 13.2 was released. In 2023, mathematica 13.3 was released.

The reader is urged to read Source 04 which is an old (but useful) introduction to mathematica by Stephen Wong.
