Pi Approximation with a series involving factorials Write a Python-3 code to calculate PI with the expression: This problem it is forbidden to use the factorial function of the library . This function will be used in the next problem. (i!) 22i+1(2i+1) ! \# An incomplete solution that was discussed is shown below for N=3 : \# FILE: PI_factorials.py \# Complete the code \#num=numerator of each term Pi Approximation with a series involving factorials Escriba un cdigo en Python-3 para calcular PI con la expresin: 2=21i=0N=(2i+1)!(i!)22i+1 Para este problema esta prohibido usar la funcin factorial de la libreria. Esta funcin se usar en el siguiente problema. \# Una solucin incompleta y que se discuti en clases se muestra abajo para N=3 : \# FILE: PI_factorials.py \# Completar el codigo N=3 P=1 for i in range (1,N+1,1) : P=Pi num =P22(i+1) \# num=numerator of each term print("numerator for i=",i, "is", num)
