Derivative 

Note: This definition of derivative is alternate to the mathematical type of derivative.

Along the lines of an integral but much more common. To take a derivative, take something that does something and do what it does back to that same thing. For clarity see examples.

A: I just took a derivative by cutting a knife.
B: Well I just took a derivative by taking a picture of a camera.
C(Math Major): What the hell are you two talking about?

Donatello from Ninja Turtles, "Too derivative"

Yo, that old navy shirt is too derivative. It's one solid color with a horizontal line of another color.

derivative 

1. In calculus, the slope of a function at a point. It is found by taking the limit of (f(x + h) - f(x)) / ((x + h) - x) where h (also seen as delta x) approaches 0.

Notations for a derivative include dy/dx and f'(x) (f prime of x)

2. The mathematical incarnation of Satan Himself

1.
f(x) = 3x^3 - 4x^2 + 2x -6 //function
f'(x) = 9x^2 - 8x + 2 //first derivative
f''(x) = 18x - 8 //second derivative
f'''(x) = 18 //third derivative

2. Teacher: Today, we're going to do derivatives

Math teacher: Change of plans! We're going to rock out to Zeppelin and have a LAN party on the school's sweet new laptops for the next hour!
Students: Hooray!

Derivative 

An insipid part of Calculus that most definitely should NOT be looked at during the summer. INTEGRAL to achieving a 5 on the AP Calculus 1 exam, this term is most commonly used by nerds of the highest degree. Beware.

I damn near had an orgasm once I found the derivative of the equation. Heaven on Earth!

Derivative 

1. The equation of the slope of a line, found by taking the limit as "h" approches 0 of the quantity "f(x + h) - f(x)" devided by "h." It was developed simultaniously by two european guys with funny names.

2. One of the few torture devices still in common use in "civilization."

1. If "f(x)" = "y" = "x^2 + 5x + 3" then it's derivative, "f'(x)" or "dy/dx" is "2x + 5"

2. Fuck my math teacher, if he gives us any more calculus homework I am going to diferentiate my foot up his ass!

derivative 

Term used by musical elitists to down bands for having any arbitrary similarities to any bands from yesteryear. Frequently used in the comments section of music videos hosted on YouTube by people who have nothing better to do in their lives than argue on the interweb

ZOMG YOU ACTUALLY LIKE INTERPOL?!?!!1? THEY'RE SOOOOOO DERIVATIVE. I MEAN C'MON, THEY TOOOOOOOOTALLY SOUND EXACTLY LIKE JOY DIVISION EXCEPT FOR THE FACT THAT JOY DIVISION IS AUTOMATICALLY BETTER BECAUSE THEY CAME FIRST.

Derivative 

Abstract Definition: For any smooth and differentiable mapping f:R->R, the derivative is an operator d/dx that takes f to df/dx, defined by the limit of the difference quotient f(x+h)-f(x)/h as h approaches 0.

Geometric Definition: The slope of the tangent line at any point of the graph of a function.

The Derivative of x^2 is 2x.
