Webb7 apr. 2024 · Etymology 2 Symbol . φ (mathematics) Euler's totient function, an arithmetic function that counts totatives; Ancient Greek Etymology . Derived from its majuscule counterpart Φ. Letter . φ • (ph) (lowercase, uppercase Φ) Lower-case phi , the 21st letter of the ancient Greek alphabet. In statistics, a standard normal table, also called the unit normal table or Z table, 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 distribution, and by extension, any normal distribution. Since probability tables cannot be printed for every normal distribution, as there are an infinite variety of normal distributions, it is c…

In the case p = 2, this is always a power of 2. If p is an odd prime, you need k = 1, and p − 1 must be a power of 2, so p is a Fermat prime. Now use the fact that ϕ is multiplicative.
