Program Code – Understanding Cotangent: A Mathematical Perspective for Coders

import math

# Function to calculate cotangent
def calculate_cotangent(angle_degrees):
    '''
    Calculates the cotangent of the given angle in degrees.

    :param angle_degrees: Angle in degrees for which the cotangent is to be calculated
    :return: The cotangent of the angle
    '''

    # Convert degrees to radians for the math trigonometric functions
    angle_radians = math.radians(angle_degrees)

    # Check if the angle is close to 90 degrees or a multiple thereof to avoid division by zero
    if angle_radians % (math.pi / 2) == 0:
        return 'undefined'  # Cotangent is undefined for 90 degrees and its multiples

    # Calculate cotangent by dividing the cosine of the angle by the sine of the angle
    cotangent = math.cos(angle_radians) / math.sin(angle_radians)
    return cotangent

# Test cases for the function
angles = [0, 30, 45, 60, 90, 180]
cotangents = {}

# Calculate cotangents for the provided angle test cases
for angle in angles:
    cotangents[angle] = calculate_cotangent(angle)

# Output the results
for angle, cot in cotangents.items():
    print(f'The cotangent of {angle} degrees is: {cot}')

Code Output:

The cotangent of 0 degrees is: undefined
The cotangent of 30 degrees is: 1.7320508075688774
The cotangent of 45 degrees is: 1.0
The cotangent of 60 degrees is: 0.5773502691896257
The cotangent of 90 degrees is: undefined
The cotangent of 180 degrees is: undefined

Code Explanation:

The program begins by importing the math module, which offers access to various mathematical operations and constants.

The calculate_cotangent function is the centerpiece of this script—it calculates the cotangent of an angle provided in degrees. The function first converts the angle from degrees to radians, as the math module’s trigonometric functions operate in radians.

In mathematical terms, cotangent is the reciprocal of the tangent, which is the ratio of the adjacent side to the opposite side in a right-angled triangle. Trigonometrically, it can be expressed as the quotient of the cosine and sine of an angle. Yet, there’s a twist—the cotangent is undefined for angles that are an exact multiple of 90 degrees (π/2 radians), as this would imply division by zero since the sine of 90 degrees is zero. To sidestep that blunder, the program checks for this condition and returns ‘undefined’ if the angle matches it.

Once clear of potential singularities, the cotangent is computed gracefully by dividing the cosine of the given angle by its sine, courtesy of math.cos() and math.sin().

To demonstrate the function’s capabilities, I’ve created an angles list containing a set of angles in degrees. These angles are iteratively processed, invoking the calculate_cotangent function and storing the return values in a cotangents dictionary where each angle is a key.

Finally, the program prints out the cotangents for the provided test angles in a readable format, making the output easily interpretable to a budding coder or even a seasoned pro keeping their skills sharp. And voilà, you’ve got a mini cotangent calculator right in your script!
