note: must solve the problem through the hint

solve in python

b) Consider the expression given below. This formula is used to compute the approximate value of 1. Write a function named approx_pi(), that uses this formula to compute and returns an approximate value. (10 Marks) (Hint: You need to import math module for computing square root. Compute factorial using another user defined function of factorial. Use a while loop to compute the summation, loop run until the absolute value in summation becomes less than 1e-15) runs 1 = 2v2 (4k)!(1103 + 26390k) 9801 k=0 (k!)43964k TT
