Consider the case where we have a value x and we need to determine the sum of the sine(x) series. There are numerous terms in a sine(x) series such that,

sine(x) = x− x^3/fact(3) + x^5/fact(5) −x^7/fact(7).....

To begin solving the specific series-based problem, we will take the degree as input and convert it to radian. To obtain the sum of the entire number of terms in this series, we shall iterate through all of the given terms and obtain the sum by operations.

Given a number x in degrees and number of terms, the task is to print the sum of sine series in python

**Examples:**

**Example1:**

**Input:**

enter the number of degrees = 55 enter number of terms = 15

**Output:**

The sum of sine series of 55 degrees of 15 terms = 0.82

**Example2:**

**Input:**

enter the number of degrees = 45 enter number of terms = 12

**Output:**

The sum of sine series of 45 degrees of 12 terms = 0.71

### 1)Printing sum of sine series in Python (Static input)

**Approach:**

- Give the degree value of x and the number of terms as static and store them in separate variables.
- As parameters, pass these values to the sine function.
- Create a sine function and then, using a for loop, convert degrees to radians.
- Then apply the sine formula expansion to each term and add them to the sum variable.
- Then print the expansion’s total sum.
- Exit of program.

**Below is the implementation:**

# importing math module import math # function which returns sum of sine series def sumsine(degrees, terms): # taking a variable which stores sum of sine series sumSeries = 0 for i in range(terms): # getting sign signofNum = (-1)**i # pie value pievalue = 22/7 # degree value of given number degval = degrees*(pievalue/180) sumSeries = sumSeries + ((degval**(2.0*i+1)) / math.factorial(2*i+1))*signofNum # returning the sum of sine series return sumSeries degrees = 30 terms = 10 print(round(sumsine(degrees, terms), 2))

**Output:**

The sum of sine series of 30 degrees of 10 terms = 0.5

**Explanation:**

- The user must provide the value of x in degrees and the number of terms, which will be saved in separate variables.
- These values are supplied as arguments to the sine functions.
- A sine function is built, and a for loop is used to convert degrees to radians and calculate the values of each term using the sine expansion formula.
- The sum variable is added to each term.
- This process is repeated until the number of phrases equals the number specified by the user.
- The total sum of sine series is printed

### 2)Printing sum of sine series in Python (User input)

**Approach:**

- Scan the degree value of x and the number of terms using int(input()) and store them in separate variables.
- As parameters, pass these values to the sine function.
- Create a sine function and then, using a for loop, convert degrees to radians.
- Then apply the sine formula expansion to each term and add them to the sum variable.
- Then print the expansion’s total sum.
- Exit of program.

**Below is the implementation:**

# importing math module import math # function which returns sum of sine series def sumsine(degrees, terms): # taking a variable which stores sum of sine series sumSeries = 0 for i in range(terms): # getting sign signofNum = (-1)**i # pie value pievalue = 22/7 # degree value of given number degval = degrees*(pievalue/180) sumSeries = sumSeries + ((degval**(2.0*i+1)) / math.factorial(2*i+1))*signofNum # returning the sum of sine series return sumSeries degrees = int(input("enter the number of degrees = ")) terms = int(input("enter number of terms = ")) print("The sum of sine series of ", degrees, "degrees", "of", terms, "terms =", round(sumsine(degrees, terms), 2))

**Output:**

enter the number of degrees = 55 enter number of terms = 15 The sum of sine series of 55 degrees of 15 terms = 0.82
