Výpočet tangensu 15 stupňov
Urč presnú hodnotu:
\( \normalsize\tg15\degree \)
\( \frac{1\ −\ \frac{\sqrt{3}}{3}}{\frac{1}{2}} \)
\( 2 · \left (1 − \frac{\sqrt{3}}{3} \right) \)
\( \normalsize2-\frac{\sqrt3}{3} \)
\( \frac{1\ +\ \frac{\sqrt{3}}{2}}{\frac{1}{2}} \)
\( 2 · \left (1 + \frac{\sqrt{3}}{2} \right) \)
\( \normalsize2+\sqrt3 \)
\( \frac{1\ −\ \frac{\sqrt{3}}{2}}{\frac{1}{2}} \)
\( 2 · \left (1 − \frac{\sqrt{3}}{2} \right) \)
\( \normalsize2-\sqrt3 \)
\( \frac{1\ −\ \frac{\sqrt{2}}{2}}{\frac{1}{2}} \)
\( 2 · \left (1 − \frac{\sqrt{2}}{2} \right) \)
\( \normalsize2-\sqrt2 \)
