trigonometry\nthe sine function\nwhat is sin 60°?\n(1 point)
Answer
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})
