Odchýlka telesovej a stenovej uhlopriečky v kocke s hranou
\(a\) je
\(\alpha \).
Potom platí:
\(\mathop{\mathrm{tg}}\nolimits \alpha = \frac{\sqrt{2}}
{2} \)
\(\sin \alpha = \frac{\sqrt{3}}
{2} \)
\(\cos \alpha = \frac{\sqrt{5}}
{3} \)
\(\mathop{\mathrm{cotg}}\nolimits \alpha = \sqrt{3}\)
\(\alpha = 45^{\circ }\)
