WebJan 22, 2024 · The prime-counting function \(\pi(x)\) appearing in the Prime Number Theorem (Theorem 1.11.3) and the prime-generating functions imagined and studied in Section 1.14 are by no means the only functions studied in number theory. Mathematicians through history have profitably looked at several additional functions tied to our key … WebEuler's totient function (also called phi-function or totient function) takes a single positive integer n n as input and outputs the number of integers present between 1 1 and n n that are co-prime to n n. Note: 2 positive integers a and b are said to be co-prime if their greatest common factor/divisor is equal to 1, that is, triage system in the philippines
