Imam manjih problema sa 15. zadatkom na 64. strani:
Citat:
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.

Code:
# pi_approximation

# this series: 4/1 - 4/3 + 4/5 - 4/7

for i in range(1, n+1, 2):

print("Approximate value of pi is: " + str(approx))
print("Deviation from Pi is: " + str(math.pi - approx))
