To complete the equivalence statement:
- We know that \(\frac{\pi}{3}\) radians is equivalent to \(60^\circ\).
So the first part of the statement is: \[ \cos 60^\circ = \]
- Next, we can find the exact value of \(\cos \frac{\pi}{3}\). The cosine of \(\frac{\pi}{3}\) is: \[ \cos \frac{\pi}{3} = \frac{1}{2} \]
Putting it all together, we have: \[ \cos 60^\circ = \cos \frac{\pi}{3} = \frac{1}{2} \]
Thus, the completed statement is: \( 60^\circ = \cos \frac{\pi}{3} = \frac{1}{2} \).
