Question

python
def create_fourier_dataset(x, max_val=7):
    """
    Return the sum of sin(n*x)/n where n = 1,2,3,4,5... max_val
    Remember, n is a scalar quantity (float/int). x is a NumPy array and you should return an equal length NumPy array

    :param x: numpy array
    :param max_val: The maximum value
    :return: a tuple with two numpy arrays x and the sum

    """

# importing numpy
import numpy as np


# the function asked in question
def create_fourier_dataset(x, max_val = 7):

    # initialising list to store the sums
    sum = []

    # iterating through every element in array 'x'
    for i in x:
        # initialising variable to '0'
        s = 0
        # calculating the value
        for n in range(1, max_val+1):
            s = s + (np.sin(n*i))/n
        # adding value to array
        sum.append(s)

    # creating numpy array : sum
    sum = np.array(sum)
    # creating tuple of two numpy arrays : x and sum
    result = (x, sum)
    # returning tuple
    return result


# testing the function
x = np.array([1, 2, 3, 4, 5])
result = create_fourier_dataset(x)
print(result)
