 Calculus
Calculus answers two main questions about functions. (1) How steep is a function at a point? (2) What is the area under the graph over some region? The first question is answered using the derivative and to answer the second question we use the integral.

 Cross Product
Given two nonzero vectors in two or three dimensions, their cross product is a vector with magnitude equal to the product of the magnitudes of the vectors times the sine of the angle between the vectors and direction perpendicular to the vectors.

 Dot Product
Given two nonzero vectors in two or three dimensions, their dot product is the product of the magnitudes times cosine of the angle between the two vectors.

 Goldbach conjecture
Every even number is the sum of two primes. In the nearly 300 years since the conjecture was formulated, nobody has ever proved it.

 Line
We can create a one-dimensional object called a line by stringing an infinite number of points along a particular dimension.

 Linear systems
A collection of 2 or more linear equations

 Logarithm
By definition, when we say "log base b of x equals y", that's the same thing as saying "b to the y equals x". So if you want to find log base b of x, you're asking "what power do you have to raise b to in oder to get x?"

 Logarithm
"The base of the log raised to the power of what's on the other side of the equal sign will equal the number that the log is operating on."

 Partial derivative
(1) partial derivative of f with respect to x, f sub x, partial f over partial x. (2) f sub xx, partial squared f over partial x squared. (3) f sub xy, partial squared f over partial y partial x.

 Plane
By stringing an infinite number of lines along a dimension perpendicular to the line, a two-dimensional object called a plane can be obtained. And then if we string an infinite number of planes in either direction, we get three dimensional space.

 Point
A point is nothing more than a location in space. It is zero-dimensional, meaning that it has no dimensions of any kind. We represent points with dots and some capital letter.

 Prime number theorem
The number of prime numbers less than a certain natural number is asymptotically equivalent to x/ln(x).
