Answer: \frac{\sqrt{3} }{2}

Step-by-step explanation:

To find sin(60), you need to know the unit circle. Sin(60) is the same as sin(π/3). On the unit circle, sin(π/3) is √3/2. We know this because the coordinates are (cos, sin). Sin is the y coordinate.

Answer:

\huge\boxed{\sin60^o=\dfrac{\sqrt3}{2}}

Step-by-step explanation:

Let's take a right triangle with acute angles 30° and 60°.

We know that the ratio of the sides of such a triangle is 2 : 1 : √3

<em>(look at the picture)</em>

We know:

sine=\dfrac{opposite}{hypotenuse}

In this triangle we have:

opposite=a\sqrt3\\hypotenuse=2a

Substitute:

\sin60^o=\dfrac{a\sqrt3}{2a}         <em>cancel </em><em>a</em>

\sin60^o=\dfrac{\sqrt3}{2}

posledela

9514 1404 393

Answer:

  0

Step-by-step explanation:

The function is defined everywhere except at x=-6. The limit value is the function value at that point.

  f(6) = (6^2 -36)/(6 +6) = 0/12 = 0

The limit of the function is 0 as x → 6.
