Write the equation of the trigonometric graph

**Instruction: Write the equation of the trigonometric graph.**

**Detailed Analysis of the Graph:**

The graph provided is a trigonometric function with the following detailed characteristics:

1. **Axes Information:**
   - The horizontal axis is labeled as \( x \).
   - The vertical axis is labeled as \( y \).

2. **Grid and Scale:**
   - The grid lines on the graph help to understand the scale and periodicity of the function.
   - The \( x \)-axis has critical points marked at intervals of \(\frac{\pi}{2}\) ranging from \(-2\pi\) to \(6\pi\). Specifically, notable points include \(-2\pi\), \(-\frac{3\pi}{2}\), \(-\pi\), \(-\frac{\pi}{2}\), \(0\), \(\frac{\pi}{2}\), \(\pi\), \(\frac{3\pi}{2}\), \(2\pi\), \( \frac{5\pi}{2}\), \(3\pi\), \(\frac{7\pi}{2}\), \(4\pi\), \(\frac{9\pi}{2}\), \(5\pi\), \(\frac{11\pi}{2}\), and \(6\pi\).

3. **Wave Characteristics:**
   - The graph represents a periodic wave.
   - From observation, each complete cycle spans a distance of \(2\pi\) units along the \( x \)-axis.
   - The amplitude (maximum |y| value reached) of the wave is 1, which is observed from the peak and trough values at \(1\) and \(-1\) respectively.
   - The graph consistently crosses the \( x \)-axis at multiples of \( \pi\) (i.e., \(-2\pi\), \(-\pi\), \(0\), \(\pi\), \(2\pi\), \(3\pi\), etc.)

4. **Type of Trigonometric Function:**
   - The wave appears sinusoidal in nature, suggesting it may either be a sine or cosine function.
   - Given it crosses the origin \( (0,0) \), this indicates the function is likely a sine function (since \(\sin(0)
