2. One of the few torture devices still in common use in "civilization."
2. Fuck my math teacher, if he gives us any more calculus homework I am going to diferentiate my foot up his ass!
Notations for a derivative include dy/dx and f'(x) (f prime of x)
2. The mathematical incarnation of Satan Himself
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 book, as ceiling clouds over and turns red: MAY THE DEMONIC ARMIES OF HELL MARCH ACROSS YOUR MORTAL PLANE, CREATION CHAOS AND DESTRUCTION AND DRINKING THE BLOOD OF THE INNOCENT AND-
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!
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.
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?
