My Python Code

Placeholder

print("This is just a placeholder.")

Remember

Remember is a place I put random stuff that I find interesting in case I forget about it or some thing I would like research more in depth later.

$\sum _{n=0}^{\infty }2^{n}=-1$ .

$5!=1\times 2\times 3\times 4\times 5=120$

$\Pi =3.14159265358979$ I'm working on memorizing 25 digits of π

$\lfloor 1.4\rfloor =1$ The floor and ceiling functions give us the nearest integer up or down.

$\lceil 1.4\rceil =2$ The floor and ceiling functions give us the nearest integer up or down.

21, 4, 0, and −2048 are integers, while 9.75, 5 ¹⁄₂, and √2 are not.

ℕ or N means either { 0, 1, 2, 3, ...} or { 1, 2, 3, ...}.

he choice depends on the area of mathematics being studied; e.g. number theorists prefer the latter; analysts, set theorists and computer scientists prefer the former. To avoid confusion, always check an author's definition of N.

ℤ or ℤ means {..., −3, −2, −1, 0, 1, 2, 3, ...}.

ℤ⁺ or ℤ^> means {1, 2, 3, ...} .

ℤ^* or ℤ^≥ means {0, 1, 2, 3, ...} .

x ≤ y means x is less than or equal to y.

x ≥ y means x is greater than or equal to y.

(The forms <= and >= are generally used in programming languages, where ease of typing and use of ASCII text is preferred.)

${\frac {1}{3}}+{\frac {1}{3}}+{\frac {1}{3}}=1$

The PlayStation is a home video game console developed and marketed by Sony Computer Entertainment. It was released in Japan on 3 December 1994, and most of the world in 1995. Sony began developing it after a failed venture with Nintendo to create a CD-ROM add-on in the early 1990s. The console was primarily designed by Ken Kutaragi and his team in Japan, while additional development was outsourced in the United Kingdom. An emphasis on 3D polygon graphics was placed at the forefront of the console's design. The PlayStation signalled Sony's rise to power in the video game industry. It received acclaim and sold strongly; in less than a decade, it became the first computer entertainment platform to ship more than 100 million units. Its use of compact discs heralded the game industry's transition from cartridges. The PlayStation's success led to a line of successors, beginning with the PlayStation 2 in 2000. (Full article...)
