Question
for the following graph listed. Amplitude in state the equation for the graph in both of the following forms
![For the following graph, list the period and amplitude, and state the equation for the graph in both of the following forms:
1. **Period:**
\[
\frac{\pi}{3}
\]
2. **Amplitude:**
\[
2
\]
### Equations:
(a) **Equation as a sine function:**
\[
y = A \sin Bx
\]
(b) **Equation as a cosine function:**
\[
y = A \cos Bx
\]
### Graph Explanation
The graph displays a trigonometric wave (sine or cosine) with the following characteristics:
- **Amplitude:** The peak of the wave reaches 2 units from the horizontal axis.
- **Period:** The wave completes one full cycle from \(-\pi\) to \(+\pi\), equivalent to a period of \(\frac{\pi}{3}\).
The horizontal x-axis intersects the wave at intervals labeled in increments of \(\frac{\pi}{3}\). The vertical y-axis marks the amplitude, extending from -2 to 2.](https://content.bartleby.com/qna-images/question/a29f41e7-bda7-4f38-a62b-8b600b009863/a3ca54f4-7ffd-4f87-8170-ee792b7d4924/zn9ouya_thumbnail.jpeg)
