Allgemeine Lösung für

cos (b) = \frac{3}{5}

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

b = arccos (\frac{3}{5}) + 2 πn, b = 2 π - arccos (\frac{3}{5}) + 2 πn

b = arccos (\frac{3}{5}) + 2 πn, b = 2 π - arccos (\frac{3}{5}) + 2 πn

Zeige Lösungen in Dezimalform

b = 0.92729 \dots + 2 πn, b = 2 π - 0.92729 \dots + 2 πn

arctan (1 - x) + arctan (1 + x) = arctan (\frac{1}{8})

5 sin (4 x) = 2

2 cos^{2} (x) - 3 \cdot sin^{2} (x) - 2 = 0

so l v e f or x, lo g_{10} (y) = arctan (x) + c

2 sin (x) = \frac{( 4 sin ( x ) - cos ( x ) )}{2}
