Write a program to print the sum of the series 1-x¹/2! + x²/3!-x/4…..xn/(n + 1)! exponential series.

Q. Write a program to print the sum of the series 1-x¹/2! + x²/3!-x/4…..xn/(n + 1)! exponential series.

Answer :-

import math
x = int(input("Enter x :-"))
n = int(input("Enter n :-"))
sum = 0

for i in range(n+1):
    if (i+1) % 2 == 0:
        num = (x ** i) / math.factorial( i+1 )
        sum -= num
    else :
        num = (x ** i) / math.factorial( i+1 )
        sum += num
print("Sum :-", sum)

Output :-

Enter x :-2
Enter n :-3
Sum :- 0.3333333333333333
>>>

Enter x :-5
Enter n :-25
Sum :- 0.19865241048416357
>>>
