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.
