$\cos30^\circ=\frac{v}{a}=\frac{\frac{a\sqrt{3}}{2}}{a}=\frac{a\sqrt{3}}{2}\cdot \frac{1}{a}=\frac{\sqrt{3}}{2}$

$\tan30^\circ=\frac{\frac{a}{2}}{v}=\frac{\frac{a}{2}}{\frac{a\sqrt{3}}{2}}=\frac{a}{2}\cdot\frac{2}{a\sqrt{3}}=\frac{1}{\sqrt{3}}=\frac{\sqrt{3}}{\sqrt{3}\cdot\sqrt{3}}=\frac{\sqrt{3}}{3}$

$\cot30^\circ=\frac{v}{\frac{a}{2}}=\frac{\frac{a\sqrt{3}}{2}}{\frac{a}{2}}=\frac{\sqrt{3}}{2}\cdot\frac{2}{1}=\sqrt{3}$

Sam izračunaj $\cos30^\circ$, $\tan30^\circ$ in $\cot30^\circ$.

Izračunaj še $\cos60^\circ$, $\tan60^\circ$ in $\cot60^\circ$.
