Revision as of 00:40, 17 September 2007

I took seven courses in calculus and linear algebra while attending university. This subject was, by far, my strongest. This category will contain articles pertaining to the subject of mathematics. I will use this category mainly for my easy reference.

Sub-Categories

CAS and numerical analysis

  • wikipedia:GNU Octave — a free computer program for performing numerical computations which is mostly compatible with MATLAB
  • wikipedia:Mathomatic — a free, portable, general purpose computer algebra system (CAS)

Misc

Note: Sandbox entry

Al-Khwārizmī's method of solving linear and quadratic equations worked by first reducing the equation to one of six standard forms (where b and c are positive integers)

  • squares equal roots (x2 = bx)
  • squares equal number (x2 = c)
  • roots equal number (bx = c)
  • squares and roots equal number (x2 + bx = c)
  • squares and number equal roots (x2 + c = bx)
  • roots and number equal squares (bx + c = x2)

Cool equations and numbers

  • Euler's identity: eiπ + 1 = 0
  • 163
  • Khinchin's constant, K ~2.685252...
  • The Euler-Mascheroni Constant, γ ~0.577215...
  • The Monster, |M|=808017424794512875886459904961710757005754368000000000
  • The Oddest Prime: 2
  • Feigenbaum's constant, δ ~4.669201...
  • (pi)^2/6
  • 78,557
  • 691
  • The Golden Ratio, φ 1.618...

Arithmetic

  • Addition:
   addend
 + augend
----------
 = sum
  • Subtraction:
   minuend
 - subtrahend
--------------
 = difference
  • Multiplication:
   multicand
 * multiplier
--------------
 = product
  • Division:
   dividend
 / divisor
-------------
 = quotient

Mental calculation

Wikipedia and its sister project, WikiBooks, have many really good articles on just about everything related to mathematics. I will list some of the best articles (and categories) here:
