Draw the graph of `y=3Sin2x`

Explanation

To draw the graph of the function \( y = 3 \sin(2x) \), we will follow these steps:

### Step 1: Understand the Function
The function \( y = 3 \sin(2x) \) is a transformation of the basic sine function. The coefficient 3 indicates that the amplitude of the sine wave is 3, and the coefficient 2 indicates that the period of the sine wave is altered.

### Step 2: Determine the Amplitude and Period
- **Amplitude**: The amplitude is the maximum value of the sine function, which is given by the coefficient in front of the sine function. Here, the amplitude is 3.
- **Period**: The period of the sine function is calculated using the formula \( \frac{2\pi}{b} \), where \( b \) is the coefficient of \( x \). Here, \( b = 2 \), so the period is:
