Question #b668b

Answer 1

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.
