In a previous paper we proved some Ramanujan{Orr formulas for 1=ˇ but we could not prove some others. In this paper we give a variant of the method, prove several more series for 1=ˇof this type and explain an experimental test which helps to discover 2019-03-05 Ramanujan’s Formula for Pi. First found by Ramanujan. It’s my favourite formula for pi. Active 6 years, 8 months ago. Viewed 2k times 0. For one of my programs in my Computer Science class I have to calculate the value of pi using the following formula, I'm having trouble with the math equation in java. Here's the math This is our fifth episode in the series "Amazing Moments in Science": Ramanujan and the Number Pi• Watch more videos of the series: http://bbva.info/2wTWldgA Convergents of the pi continued fractions are the simplest approximants to pi.

Other formulas for pi: The accuracy of π improves by increasing the number of digits for calculation. In 1914, the Indian mathematician Ramanujan discovered the formula for computing Pi that converges rapidly.

In a famous paper of $1914$ Ramanujan gave a list of $17$ extraordinary formulas for the number $\pi$.

Here is a Ramanujan's identity. $$\frac{2 \sqrt{2}}{9801} \sum_{k=0}^{\infty} \frac{(4 k) !(1103+26390 k)}{(k !)^{4} 396^{4 k}}=\frac{1}{\pi}$$ i want to learn why this formula is perfect.I think left side gives infinite sum the right hand side is finite result and expressed in ${\pi}$ term.

Al parecer, Ramanujan ahora había aceptado la propuesta; como Neville dijo, "Ramanujan no necesitaba ser convencido, y la oposición de sus padres había sido retirada".  Al parecer, la madre de Ramanujan tuvo un sueño vívido en el que la diosa de la familia, Namagiri Thayar , le ordenó que "no prolongase más tiempo la separación entre su hijo y el cumplimiento del propósito de su Approximating Pi by Using Ramanujan's Formula.

approximation formula for pi (the Ramanujan formula): Note that this is a series approximation - we calculate a series of terms for k = 0, k = 1, k = 2, Al parecer, Ramanujan ahora había aceptado la propuesta; como Neville dijo, "Ramanujan no necesitaba ser convencido, y la oposición de sus padres había sido retirada".

This means that π can not be written as a ratio of two  A Ramanujan-type formula due to the Chudnovsky brothers used to break a world record for computing the most digits of pi: For implementations, it may help to  Archimedes computed π very accurately. Much later, Ramanujan discovered several infinite series for 1/π that enables one to compute π even more accurately. Article discusses the theoretical background for generating Ramanujan-type formulas for 1/pi^p and constructs series for p=4 and p=6. 17 May 2012 In 1914, Ramanujan published a paper entitled“Modular equations and approximations to π” in England .
