# Question #b668b

The amplitude is $\frac{1}{2}$.
The positive value of the $\textcolor{g r e e n}{c o e f f i c i e n t}$ of $\sin \left(x\right)$ is the amplitude of a sin curve. Looking at the equation $y = \textcolor{g r e e n}{\frac{1}{2}} \sin \left(x\right)$, we can see that the coefficient is $\textcolor{g r e e n}{\frac{1}{2}}$.
Check it out on the graph below - we can see that the y values of the curve vary between $\frac{1}{2}$ and $- \frac{1}{2}$, confirming what we determined above.
