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.
Contents
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)

External links
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:
- WikiBooks - Wikiversity - School of Mathematics
- Wikipedia category on mathematics
- Wikipedia article on mathematics
Other
- MathWorld — by Wolfram Research
- The Wolfram Integrator — by Wolfram Research
- PlanetMath.org — a collaboratively created, virtual community which aims to help make mathematical knowledge more accessible.
- PlanetPhysics.org — a collaboratively created, virtual community which aims to help make physics knowledge more accessible.
- The Octomatics Project — about a new number system which has a lot of advantages over our old decimal system.
