WebbThe PHI function is categorized as a Statistical function that returns the value of the density function for a standard normal distribution for a given number. For example, when you have the given number(x) equal to 1 and use the PHI function, then the value of the probability density function would be equivalent to 0.241971. WebbThat is, \phi (n) ϕ(n) is the number of m\in\mathbb {N} m ∈ N such that 1\le m \lt n 1 ≤ m < n and \gcd (m,n)=1 gcd(m,n) = 1. The totient function appears in many applications of …

Webb17 jan. 2024 · There are two interesting observations about the phi() function that you should know: The larger the value of N, the more difficult it is to find phi(N). If N is a prime number, then it is easy to find phi(N). By definition, the only number a prime has common factors with except 1 is itself. So, the value of phi(N), where N is a prime number ... WebbTo resolve this, a special statement is inserted in the last block, called a Φ (Phi) function.
