Question

trigonometry
the sine function
what is sin 60°?
(1 point)

Explanation:

Step1: Recall the definition of sine in a unit - circle

In the unit - circle, for a point \((x,y)\) on the terminal side of an angle \(\theta\), \(\sin\theta=y\).

Step2: Identify the \(y\) - coordinate for \(60^{\circ}\)

From the given unit - circle diagram, for the angle \(60^{\circ}\), the point is \((\frac{\sqrt{3}}{2},\frac{1}{2})\).

Answer:

\(\frac{1}{2}\)
