    en.wikipedia.org/wiki/Multiplicative_group_of...

    In modular arithmetic, the integers coprime (relatively prime) to n from the set of n non-negative integers form a group under multiplication modulo n, called the multiplicative group of integers modulo n. Equivalently, the elements of this group can be thought of as the congruence classes, also known as residues modulo n, that are coprime to n .

    Standard normal table. In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution. It is used to find the probability that a statistic is observed below, above, or between values on the standard normal ...

  8. 1 − 2 + 3 − 4 + ⋯ - Wikipedia

    The idea becomes clearer by considering the general series 1 − 2x + 3x 2 − 4x 3 + 5x 4 − 6x 5 + &c. that arises while expanding the expression 1 ⁄ (1+x) 2, which this series is indeed equal to after we set x = 1. There are many ways to see that, at least for absolute values | x | < 1, Euler is right in that

    A total of 558 Z-5 were built. A few Z-5 helicopters were modified to carry machine-guns and rocket pods. During the Chinese-Western rapprochement, one Z-5 was refitted with a Pratt & Whitney Canada PT6T-6 "Twin Pac" turbo-shaft engine in 1979. Some sources refer to this as the Z-6, but this variant was discontinued after its first model.
