    look on the unit circle to find where the second coordinate is \(-\frac{\sqrt{3}}{2}\) and the first coordinate is \(\frac{1}{2}\)

    oops sorry, should be second coordinate is \(\frac{\sqrt{3}}{2}\) and first coordinate is \(\frac{1}{2}\)

    look at the angle of \(\frac{\pi}{3}\) and you will see that the second coordinate is \(\frac{\sqrt{3}}{2}\) and the first coordinate is \(\frac{1}{2}\) and so \[\tan(\frac{\pi}{3})=\sqrt3\]

    oh you are working in degrees. not problem since \(\tan(60)=\sqrt3\) you know \(\tan^{-1}(\sqrt3)=60\)
