![### Question 4
**What is the period of \( y = \sin 4x \) ?**
Options:
a) \(\frac{\pi}{4}\)
b) \(\frac{\pi}{2}\)
c) \(\frac{4}{\pi}\)
d) \(\pi\)
e) \(2\pi\)
#### Explanation:
To find the period of the function \( y = \sin 4x \):
1. Recall the general form for the period of \( y = \sin (bx) \) which is \( \frac{2\pi}{b} \).
2. In this case, \( b = 4 \).
3. Therefore, the period \( T \) is calculated as:
\[
T = \frac{2\pi}{4} = \frac{\pi}{2}
\]
Thus, the correct period of the function \( y = \sin 4x \) is \(\frac{\pi}{2}\).
Therefore, the correct answer is \( \frac{\pi}{2} \).
