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)

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

Why I'm failing AP Calculus right now.

Quiz: Find the derivatives of the following.

#1: e^(-2coscsc4x)(4pitan/-7secx)^cos6x.

Me: *blank stare*

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?

Not original, over-used.

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.

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.

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!

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.
