**The Average Daily Temperature Model: A Mathematical Exploration**

Introduction

The average daily temperature in a city can be influenced by various factors, including the month of the year. In this article, we will explore a mathematical model that describes the average daily temperature as a function of the month of the year. The model is given by the equation:

${ t = 35 \cos \left(\frac{\pi}{6}(m+3)\right) + 55 }$

where $t$ is the average daily temperature in degrees Fahrenheit and $m$ is the month of the year.

Understanding the Model

The given equation is a trigonometric function that describes the average daily temperature as a cosine wave. The cosine function is a periodic function that oscillates between -1 and 1. In this case, the cosine function is scaled by a factor of 35, which means that the temperature will oscillate between -35 and 35 degrees Fahrenheit.

The argument of the cosine function is $\frac{\pi}{6}(m+3)$ . This expression represents the phase shift of the cosine wave. The phase shift is a measure of how much the cosine wave is shifted to the left or right. In this case, the phase shift is $\frac{\pi}{6}$ , which means that the cosine wave is shifted to the right by $\frac{\pi}{6}$ radians.

Analyzing the Model

To analyze the model, we need to understand the behavior of the cosine function. The cosine function has a period of $2\pi$ , which means that it repeats itself every $2\pi$ radians. In this case, the argument of the cosine function is $\frac{\pi}{6}(m+3)$ , which means that the cosine wave will repeat itself every 12 months.

The amplitude of the cosine wave is 35, which means that the temperature will oscillate between -35 and 35 degrees Fahrenheit. The average temperature is 55 degrees Fahrenheit, which means that the temperature will be above 55 degrees Fahrenheit for 6 months and below 55 degrees Fahrenheit for 6 months.

Graphical Representation

To visualize the behavior of the model, we can plot the average daily temperature as a function of the month of the year. The graph will show a cosine wave with an amplitude of 35 and a period of 12 months.

import matplotlib.pyplot as plt
import numpy as np
months = np.arange(1, 13)

temperature = 35 * np.cos(np.pi/6 * (months + 3)) + 55

plt.plot(months, temperature)
plt.xlabel('Month of the Year')
plt.ylabel('Average Daily Temperature (°F)')
plt.title('Average Daily Temperature Model')
plt.show()

In this article, we explored a mathematical model that describes the average daily temperature as a function of the month of the year. The model is given by the equation:

${ t = 35 \cos \left(\frac{\pi}{6}(m+3)\right) + 55 }$

where $t$ is the average daily temperature in degrees Fahrenheit and $m$ is the month of the year. We analyzed the behavior of the model and visualized the average daily temperature as a function of the month of the year using a cosine wave.
