Introduction

The average monthly temperature in a particular city can be modeled using a mathematical equation. In this article, we will explore the given model, discuss its implications, and provide insights into the underlying mathematics. The model is represented by the equation $$T(m)=4 \sin \left(\frac{\pi}{6} m\right)+2$$, where $m$ represents the months of the year.

Understanding the Model

The given model is a sinusoidal function, which means it oscillates between a maximum and minimum value. In this case, the function oscillates between $2-4$ and $2+4$ , with a period of $12$ months. This is because the coefficient of the sine function, $\frac{\pi}{6}$ , is multiplied by $m$ , which represents the months of the year. The period of a sinusoidal function is given by $\frac{2\pi}{b}$ , where $b$ is the coefficient of the sine function. In this case, the period is $\frac{2\pi}{\frac{\pi}{6}}=12$ months.

Analyzing the Model

To analyze the model, we need to find the maximum and minimum values of the function. The maximum value occurs when the sine function is equal to $1$ , which happens when $\frac{\pi}{6} m=\frac{\pi}{2}$ . Solving for $m$ , we get $m=3$ . Substituting this value into the equation, we get $T(3)=4 \sin \left(\frac{\pi}{2}\right)+2=6$ . Therefore, the maximum value of the function is $6$ degrees Celsius.

The minimum value occurs when the sine function is equal to $-1$ , which happens when $\frac{\pi}{6} m=\frac{3\pi}{2}$ . Solving for $m$ , we get $m=9$ . Substituting this value into the equation, we get $T(9)=4 \sin \left(\frac{3\pi}{2}\right)+2=-2$ . Therefore, the minimum value of the function is $-2$ degrees Celsius.

Graphical Representation

To visualize the model, we can plot the function using a graphing tool. The graph will show the oscillating behavior of the function, with the maximum and minimum values occurring at $m=3$ and $m=9$ , respectively.

Interpretation

The model provides a mathematical representation of the average monthly temperature in a particular city. The oscillating behavior of the function indicates that the temperature varies throughout the year, with the maximum and minimum values occurring in the summer and winter months, respectively.

Conclusion
