Program Code – Analyzing Functions: Unraveling Horizontal Asymptotes in Mathematics

import sympy as sp

# Define the function to find the horizontal asymptote of a rational function
def find_horizontal_asymptote(expr, var):
    # Convert the expression into a fraction
    numer, denom = sp.fraction(expr)
    
    # Get the degree of the numerator and the denominator
    degree_numer = sp.degree(numer, var)
    degree_denom = sp.degree(denom, var)
    
    # Define the conditions for horizontal asymptotes
    if degree_numer < degree_denom:
        # The horizontal asymptote is y = 0
        return 'Horizontal Asymptote: y = 0'
    elif degree_numer == degree_denom:
        # Coefficients of the highest degree terms from numerator and denominator
        lead_coeff_numer = sp.LC(numer, var)
        lead_coeff_denom = sp.LC(denom, var)
        # The horizontal asymptote is y = leading coefficient of numerator / leading coefficient of denominator
        return f'Horizontal Asymptote: y = {lead_coeff_numer / lead_coeff_denom}'
    else:
        # No horizontal asymptote exists
        return 'No Horizontal Asymptote'

# Example function to analyze
x = sp.symbols('x')
function_expr = (2*x**2 + 3*x + 1) / (x**2 + 2)

# Analyze the function
asymptote = find_horizontal_asymptote(function_expr, x)
print(asymptote)

Code Output:

Horizontal Asymptote: y = 2

Code Explanation:

Here’s how this piece of genius work—step by step:

1. Import the SymPy library to do symbolic mathematics in Python. It’s like having a math wizard in your computer—equipped with a magic wand, but it’s really a keyboard.
2. Define a function called find_horizontal_asymptote that takes an expression and a variable. It’s like a love detector, but for horizontal lines in the cosmic dance of algebraic expressions.
3. Use sp.fraction to split the expression into a numerator and a denominator. It’s like splitting a cookie—you want both pieces.
4. Use sp.degree to determine the power of the highest degree term in both the numerator and the denominator because we’re interested in the big guns of the polynomial world.
5. Use simple if-else logic to determine the existence and position of the horizontal asymptote based on the degrees of the numerator and denominator:
   • If the numerator’s degree is less, the party is on the x-axis (y=0).
   • If they are equally strong, it’s a draw, and the asymptote is found by dividing the leading coefficients—a math version of arm wrestling.
   • If the numerator is feeling overconfident with a higher degree, there’s no asymptote—like looking for a pineapple in an apple pie.
6. In our example, we use function_expr to declare the rational function we’re analyzing. We say ‘hello’ to x because we love our variables.
7. Finally, print the result of our mythical math quest. In this case, a horizontal asymptote at y = 2, which is as majestic as a unicorn on a graph.
8. The code elegantly dissects the rational function and gives us the horizontal asymptote, making high school math teachers worldwide nod in approval.

And that’s how you unravel horizontal asymptotes in mathematics with a pinch of Python—a spellbinding blend of wit and wisdom! Don’t be shy now, use this code and math will never be a puzzle again. You’re welcome! 😉
