The amplitude is 1/2.

Explanation:

The positive value of the color(green)[coefficient] of sin(x) is the amplitude of a sin curve. Looking at the equation y=color(green)[1/2]sin(x), we can see that the coefficient is color(green)[1/2].

Check it out on the graph below - we can see that the y values of the curve vary between 1/2 and -1/2, confirming what we determined above.
