### Analysis of Monthly High Temperatures in Atlanta for 2021

The table below provides data on the high temperatures recorded in Atlanta for each month of the year 2021. Each month is associated with its corresponding high temperature in degrees Fahrenheit.

| Month | Temperature (°F) |
|-------|------------------|
| 1     | 53               |
| 2     | 57               |
| 3     | 65               |
| 4     | 73               |
| 5     | 80               |
| 6     | 86               |
| 7     | 88               |
| 8     | 87               |
| 9     | 82               |
| 10    | 72               |
| 11    | 63               |
| 12    | 55               |

#### Objective:
Develop a trigonometric model that accurately represents the data listed above.

#### Steps to Arrive at the Solution:
1. **Identify Patterns in Data:**
   - Analyze the temperature data to recognize any cyclical and periodic patterns, typical of weather data over a year.

2. **Choose the Right Trigonometric Function:**
   - Since temperatures tend to rise and fall periodically, consider using sinusoidal functions (sine or cosine), which naturally model periodic behavior.

3. **Determine Amplitude, Frequency, Phase Shift, and Vertical Shift:**
   - **Amplitude (A)** represents half the range of temperature variation:
     \[
     \text{Range} = \text{Maximum Temperature} - \text{Minimum Temperature} = 88 - 53 = 35
     \]
     \[
     A = \frac{\text{Range}}{2} = \frac{35}{2} = 17.5
     \]
   - **Vertical Shift (D)** is the midpoint (average) of the maximum and minimum temperatures:
     \[
     D = \frac{\text{Maximum Temperature} + \text{Minimum Temperature}}{2} = \frac{88 + 53}{2} = 70.5
     \]
   - **Frequency (B)** is related to the period of the seasons; typically, for a year, the period is 12 months.
     \[
     B = \frac{2\pi}{\text{Period}} = \frac{2\pi}{12} = \frac{\pi}{6
