Basic functions and their graphs
y=x^2
(an even function : symmetric about the y-axis)
y=[x]
(Even; Symm. about the y-axis)
y=sgn(x)
(Gives the sign of the argument)
(An odd function : Symm. about the origin)

VPS 1 : Multiplying any number by 11
P.S: The number must be a 2-digit number.
Steps:
1. Add the 2-digits of the number together.
2. Place the sum of the two-digits between the 2 digits to get the answer.
Eg:
21x11->2+1=3, Answer=>231
36x11->3+6=9, Answer=>396
29x11->9+2=11(a 2-digit number, hence, 1 gets carried over), Answer=>319

36x11->3+6=9, Answer=>396
29x11->9+2=11(a 2-digit number, hence, 1 gets carried over), Answer=>319
VPS 1: Squaring Numbers Ending in 5
Steps:
1. Add 1 to the digits that come before the digit 5.(Eg. add 1 to 2 in case of 25 squared)
2. The first part of the answer is the number(consisting of the digits that come before 5)times the number you get be adding 1 to it(here, 2x3=6)
3.The second part of the answer is simply 25.
Eg 1:
For, (35)²->3+1=4, 3x4=12 , therefore answers=>1225
Eg 2:
(65)²->6+1=7, 6x7=42 , hence, answer=>4225

Vedic Mathematics : An Introduction
This post corresponds to the Public Session By Dev on 25th Jan, 2009.
The Origin
Use
The Origin
Born in the Vedic Age - There are sixteen Sutras and thirteen Sub-Sutras in the writings of "Atharva Vedas" the fourth Veda.
Atharva Veda deals with the branches like Engineering, Mathematics, sculpture, Medicine, and other sciences.
Rediscovered from the ancient Indian scriptures between by Sri Bharati Krishna Tirthaji (a scholar of Sanskrit, Mathematics, History and Philosophy)
Use
For each one of us : Time-saving; Calculations become faster
For the children : They only need to learn tables upto 9
For MBA and Economics students
Useful for those appearing for CAT (and other competitive exams) : To beat the competition by:
-Eliminating wrong answers using mental calculation
-Approximations in Data Interpretation
-Intelligent Guessing using Vedic Math
