A very powerful approximation for was developed by a brilliant mathematician named Srinivasa Ramanujan. The approximation is the following: 1 2 2 9801 N k=0 (4k)!(1103 + 26390k) (k!)43964k . Use Ramanujans formula for N = 0 and N = 1 to approximate . Compare your approximation with Pythons stored value for . Hint: 0! = 1 by definition.
