• 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.

• Digits, Numerals and Numbers

Digits make up numerals and numerals stand for an idea of a number just like letters make up words and words stand for ideas.

• Goldbach conjecture

The Goldbach conjecture says that every even number is the sum of two primes. A prime number is one that's only divisible by itself and 1.

• Golden angle Ψ

An important part is also played by the golden angle which divides the angle of 360° in the proportions of the golden section. As an angle smaller than 180° proved to be more handy in practice the smaller of the resultant angles is called the golden angle

• Golden section

A length is devided into two parts in such a way that the smaller part is to the larger part in the same proportion as the larger one is to the whole.

• Logarithm - Krista King

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?"

• Prime number theorem

The prime number theorem says that PI of x is asymtotically equivalent to x over log x. As a reminder, two sequences a sub n and b sub n are asymtotically equivalent if the limit as n goes to infinity of a sub n over b sub n is one.
