Identify a complex number that is not equal to \(\left (\cos \frac{\pi }{3} + \mathrm{i}\sin \frac{\pi }{3}\right )^{19}\).
\( \frac{1}{2} - \frac{\sqrt{3}}{2}\mathrm{i}\)
\( \cos \frac{\pi }{3} + \mathrm{i}\sin \frac{\pi }{3} \)
\( \frac{1}{2} + \frac{\sqrt{3}}{2}\mathrm{i}\)
\( \cos \left(-\frac{5\pi }{3}\right) + \mathrm{i}\sin \left(-\frac{5\pi }{3}\right) \)
