Pi function
In mathematics, at least four different functions are known as the pi or Pi function: * \pi(x)\,\! (pi function) – the prime-counting function * \Pi(x)\,\! (Pi function) – the gamma function when offset to coincide with the factorial * Rectangular function * \pi(n)\,\! – the Pisano period It may also refer to: * \prod_{n=1}^{\infty} – the Infinite product of a sequence *Capital pi notation
