Write a function estimatePi( to estimate and return the value of pi based on the formula found by an Indian Mathematician Srinivasa Ramanujan. It should use a while loop to compute the terms of the summation until the last item is smaller than 1e -15. The formula for calculating distance is given below: 7T k=0 1 22 * (4k)!(1103 + 26390k) jo 9801 (k!)43964k where k! is the factorial of k.
