Case :
Write a program that approximates the value of Π by summing the terms of this series:
4/1 – 4/3 + 4/5 – 4/7 + 4/9 – 4/11 +…
The program should prompt the user for n, the number of terms to sum, and then output the sum of the first n terms of this series. Have your program subtract the approximation from the value of math.pi to see how accurate it is.
Answer:
import math
trueValue = math.pi
def pi(n):
