The amplitude of a sine function is the absolute value of the coefficient in front of the sine term. In the function $y = \frac{5}{6} \sin(x)$, the coefficient of $\sin(x)$ is $\frac{5}{6}$.

Thus, the amplitude is:

$\text{Amplitude} = \left| \frac{5}{6} \right| = \frac{5}{6}$

So, the amplitude is $\frac{5}{6}$.

Would you like me to graph both $y = \frac{5}{6} \sin(x)$ and $y = \sin(x)$ for comparison?

Here are five related questions to expand on this:

1. How does the amplitude of a sine function affect its graph?
2. What is the period of the function $y = \frac{5}{6} \sin(x)$?
3. How would you find the phase shift of a sine function?
4. What would the amplitude be if the function were $y = -\frac{5}{6} \sin(x)$?
5. How does the amplitude of $y = \frac{5}{6} \sin(x)$ compare to that of $y = \sin(x)$?

Tip: When graphing trigonometric functions, remember that the amplitude only affects the vertical stretch or compression of the graph!
