arccos (0.5)

= arccos (\frac{1}{2})

Verwende die folgende triviale Identität:

arccos (\frac{1}{2}) = \frac{π}{3}

arccos (\frac{1}{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}

2 sin (2 x) = 1

16 cos (15 x) + 8 = 2

sin (\frac{π}{6} + \frac{π}{3})

cos^{2} (x) = \frac{1}{2}

2 sin (x) = 1
