arccos (\frac{2}{2})

Verwende die folgende triviale Identität:

arccos (\frac{2}{2}) = \frac{π}{4}

arccos (\frac{2}{2})

x - 1 - \frac{3}{2} - \frac{2}{2} - \frac{1}{2} 0 \frac{1}{2} \frac{2}{2} \frac{3}{2} 1 arccos (x) π \frac{5 π}{6} \frac{3 π}{4} \frac{2 π}{3} \frac{π}{2} \frac{π}{3} \frac{π}{4} \frac{π}{6} 0 arccos (x) 18 0^{\circ} 15 0^{\circ} 13 5^{\circ} 12 0^{\circ} 9 0^{\circ} 6 0^{\circ} 4 5^{\circ} 3 0^{\circ} 0^{\circ}

cos (\frac{π}{6})

sin (1 0^{\circ})

cos (x) cos (3 x) + sin (x) sin (3 x) = 0, 0 \leq x \leq 2 π
