In number theory, Euler's totient function counts the positive integers up to a given integer n that are relatively prime to n. It is written using the Greek letter phi as φ(n) or ϕ(n), and may also be called Euler's phi function. In other words, it is the number of integers k in the range 1 ≤ k ≤ n for which the greatest common divisor gcd(n, k) is equal to 1.[2][3] The integers k of this form are sometimes referred to as totatives of n. For example, the totatives of n = 9 are the six numbers 1, 2, 4, 5, 7 and 8. They are all relatively prime to 9, but the other three numbers in this range, 3, 6, and 9 are not, since gcd(9, 3) = gcd(9, 6) = 3 and gcd(9, 9) = 9. Therefore, φ(9) = 6. As another example, φ(1) = 1 since for n = 1 the only integer in the range from 1 to n is 1 itself, and gcd(1, 1) = 1.

Euler's totient function is a multiplicative function, meaning that if two numbers m and n are relatively prime, then φ(mn) = φ(m)φ(n).[4][5] This function gives the order of the multiplicative group of integers modulo n (the group of units of the ring ℤ/nℤ).[6] It is also used for defining the RSA encryption system.

En matemática y física, un vector es un ente matemático como la recta o el plano. Un vector se representa mediante un segmento de recta, orientado dentro del espacio euclidiano tridimensional. El vector tiene 3 elementos: módulo, dirección y sentido. Los vectores nos permiten representar magnitudes físicas vectoriales, como las mencionadas líneas abajo. En matemáticas se define vector como un elemento de un espacio vectorial. Esta noción es más abstracta y para muchos espacios vectoriales no es posible representar sus vectores mediante el módulo y la dirección. En particular los espacios de dimensión infinita sin producto escalar no son representables de ese modo. Los vectores en un espacio euclídeo se pueden representar geométricamente como segmentos de recta R, en el plano{R}^{2} (bidimensional), o en el espacio{R}^{3} (tridimensional). En física se define como el segmento de una recta, el cual se encuentra situado en el espacio de un plano ya sea bidimensional o tridimensional.

An index is a method to track the performance of a group of assets in a standardized way. Indexes typically measure the performance of a basket of securities intended to replicate a certain area of the market. These could be a broad-based index that captures the entire market, such as the Standard & Poor's 500 Index or Dow Jones Industrial Average (DJIA), or more specialized such as indexes that track a particular industry or segment.

Hi, I am Nigerian Prince and I want to give you money, but because of poor technology in my country unfortunately I am not able to give you money myself. Please be so kind to send me your bank info yourself and then I will forward you the money. Many thanks for your cooperation! Best regards, Nigerian Prince.
