Submitted by razormist on Friday, June 27, 2025 - 23:07.

In this tutorial, we will learn how to program "How to Find the Sum of Sine Series in Python" The objective is to find the sum of sine series. This tutorial will guide you step by step through the process of determining the sine series number. By the end of this tutorial, you will have a solid understanding of how to efficiently count set bits in Python, helping you strengthen your problem-solving and coding skills.

This topic is straightforward to understand. Just follow the instructions provided, and you will be able to complete it with ease. The program demonstrated will show you the efficient way to count the set bits in an integer. So, let’s dive into the coding process!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

import math
def sin(x,n):
    sine = 0
    for i in range(n):
        sign = (-1)**i
        pi=22/7
        y=x*(pi/180)
        sine = sine + ((y**(2.0*i+1))/math.factorial(2*i+1))*sign
    return sine
 
while True:
    print("\n============== Find the Sum of Sine Series ==============\n")
 
 
    x=int(input("Enter the value of x in degrees:"))
    terms=int(input("Enter the number of terms:"))
    print(round(sin(x,terms),2))
 
    opt = input("\nDo you want to try again?(yes/no): ")
           
    if opt.lower() == 'yes':
        ret=False
    elif opt.lower() == 'no':
        ret=True
        print("Exiting program....")
    else:
        print("Please enter yes/no:")
        break
 
    if ret == False:
        continue

This Python program calculates the sum of the sine series for a given angle in degrees and a specified number of terms. It uses a custom sin() function that approximates the sine value by summing the terms of its Taylor series expansion. The program continuously prompts the user to enter input values until they choose to exit.

Output:

There you have it we successfully created How to Find the Sum of Sine Series in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
