Goniometrický tvar komplexního čísla
\(z=\frac{\mathrm{i}^{12}+1}
{\mathrm{i}^{11}+1} \) je:
\(\sqrt{2}\left (\cos \frac{\pi }
{4} + \mathrm{i}\sin \frac{\pi }
{4}\right )\)
\(\cos \frac{\pi }
{2} + \mathrm{i}\sin \frac{\pi }
{2}\)
\(\sqrt{2}\left (\cos \frac{5\pi }
{4} + \mathrm{i}\sin \frac{5\pi }
{4}\right )\)
\(\sqrt{2}\left (\cos \frac{3\pi }
{4} + \mathrm{i}\sin \frac{3\pi }
{4}\right )\)
