Python Program to Find the Sum of Cosine Series

import math
def cosine(x,n):
    cosx = 1
    sign = -1
    for i in range(2, n, 2):
        pi=22/7
        y=x*(pi/180)
        cosx = cosx + (sign*(y**i))/math.factorial(i)
        sign = -sign
    return cosx
x=int(input("Enter the value of x in degrees:"))
n=int(input("Enter the number of terms:"))
print(round(cosine(x,n),2))

Output

Enter the value of x in degrees:0
Enter the number of terms:10
