Math Problem Statement

Emily is preparing for an upcoming event where she will be using props designed by someone else. She needs to find the exact calculations for an angle that has been given in radians so that she can ensure that the props are set up correctly. The angle in question is π3 radians. Emily specifically needs to know the exact value of the sine of this angle.

Find the exact value of sin(π3) .

Solution

To find the exact value of sin(π3)\sin\left(\frac{\pi}{3}\right), we can use our knowledge of trigonometric values for special angles.

The angle π3\frac{\pi}{3} radians corresponds to 60 degrees. The sine of 60 degrees is a well-known value.

sin(π3)=sin(60)=32\sin\left(\frac{\pi}{3}\right) = \sin(60^\circ) = \frac{\sqrt{3}}{2}

So, the exact value of sin(π3)\sin\left(\frac{\pi}{3}\right) is 32\frac{\sqrt{3}}{2}.
