1. Math invented by Sir Isaac Newton in the 17th century. Involves calculating "limits", numbers that are normally unable to be calculated except through differentiation.

2. The mathematics of Limits and Derivatives.

3. A freakin' impossible math class. Calculus AB is too hard, BC is impossible.

Something warm, fuzzy, and incredibly useful.
A point mass moves in the xy-plane with a velocity given by 6t2+9t+2. What's its average velocity between t=1 and t=4?

Try solving that one without calculus.

N. A field of mathematics which was devised by Isaac Newton to be used as means for social darwinism on basis of intelligence due to its impossibility to understand for persons with IQ's lower than 160 .
Baby who has an IQ of 140 couldn't understand the First Fundamental Theorem of Calculus after studying it solely for 12 hours. Todd Ericson who has an IQ above 200 understood it before he was done reading the written definition.

A field of math that's only known for being hard because the standard method of teaching it is so unnecessarily unintuitive that no one can understand the actual meaning of whatever the fuck they're doing
Newton: I just invented Calculus, a field of math so diverse that it can be applied to almost any topic from economics to biology
Literally everyone else: That's wonderful! I'm sure you'll share it with everyone and make the world a better place
Newton: Nah, I'm gonna write the first calculus textbook to be intentionally confusing and unintuitive just so my accomplishment seems more impressive.
Literally everyone else: bruh.

Calculus is awesome!
The limit as all y'all approach Calculus is equal to infinity, according to L'Hopital's Rule.

All of y'all probably don't know how to integrate dx/(x²+1)^3/2 or arcsin x dx from 0 to 1.

Derivatives also rock my world! f(x) = 4x³... f'(x) = 12x²... What is the second derivative of f(x) = 12x^4? Figure it out yourself, I'm not gonna tell you.

CALCULUS IS FUN! IT IS COOL TO DIFFERIATE AND INTEGRATE!
