 > Evaluate $\arccos{\frac{1}{2}}$ using the unit circle. 

 Taking the inverse of the above function, we get this. Because the domain of $cos$ ranges from $0$ to $\pi$ inclusive, the answer is going to be in quadrant 1 or quadrant 2. 
-$$ cos(x) = \frac{1}{2} $$
+$$ cos(a) = \frac{1}{2} $$
+When $x$ is equal to one half, the angle is equal to $\frac{\pi}{3}$.
