Beerpong Phonebook Rule

During the game of Beerpong. If one team decides not to rerack for an entire game, sinks all the cups, and wins. The opponents must take a thick phonebook across the face for punishment of the embarrassment. The opponents choose the side of the face. The rule originated from Youngstown State University in Youngstown, Ohio.
John: "Why dont you rerack, your going to lose"
Cody: "The beerpong phonebook rule is in effect, two more cups and your taking one to the face."

The game is finished, and Cody's team wins.

John: "What happens now?"
Cody: "Bend over and I'll show you!"

Cody has the phonebook in hand.

"SMACK, AAAAHHHHHHHHH!"

Half your age plus seven rule.

A mathematical equation used to find the youngest age a person can date without being considered a disgusting, cradle robbing freak. (A/2)-7=Y, where A is your age and Y is the youngest you should date.

Conversely the rule can be inverted to find the oldest age a person should date. 2(A-7)=O, where A is your age and O is the oldest you should date.
John is 26 and dating a 20 year old named Kate, (26/2)+7=20. Their relationship satisfies the half your age plus 7 rule.

Kate is 20 and dating a 26 year old named John. 2(20-7)=26. This relationships satisfies the inverse of the half your age plus seven rule.

the simple power rule

A mathematical rule useful for finding the derivative or instantaneous rate of change of a function that involves the form y = x^n. If n = 0, then the rate of change is zero, since any number x raised to the zero power is 1. To find the derivative when n is some other number other than 0, simply pull down the exponent n, multiply the entire function by n, then subtract 1 from the exponent after you pull n down and multiply. Basically:
1) y = x^n
2) y' = nx^n-1 (y' means take the derivative of the function with respect to x, so use the simple power rule!)

Piece of cake! One of the most helpful rules in calculus, because if you didn't have the simple power rule, then you would have to use the general form for a derivative, which takes alot longer than the method above.
Try these out! Just take the derivative as described above!

y = 3x^(-2)
y'= -6/(x^3)

y = 12x^0
y'= 0

y = 3x^(1/2)
y'= (3/2)x^(-1/2) or 3/2 times 1/squareroot of x
