Allgemeine Lösung für

cos (x) = 0.587

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

x = arccos (0.587) + 2 πn, x = 2 π - arccos (0.587) + 2 πn

x = arccos (0.587) + 2 πn, x = 2 π - arccos (0.587) + 2 πn

\frac{sec ( x ) + csc ( x )}{1 + tan ( x )} = sin (x)

sec (x) - \frac{sin ( x )}{cos ( x )} = cos (x)

cos (θ) = 0.4, sec (θ)

cot (θ) = \frac{1 + cos ^{2} ( θ )}{2 sin ( θ ) cos ( θ )}

sec (3 x) - csc (3 0^{\circ}) = 0, \frac{x + 35}{5}
