Allgemeine Lösung für

sec (θ) = - 2.5

sec (x) = - a \Rightarrow x = arcsec (- a) + 2 πn, x = - arcsec (- a) + 2 πn

θ = arcsec (- 2.5) + 2 πn, θ = - arcsec (- 2.5) + 2 πn

θ = arcsec (- 2.5) + 2 πn, θ = - arcsec (- 2.5) + 2 πn

cos (4 x) = 0, 0 \leq x \leq 2 π

\frac{csc ( x )}{cot ( x )} = csc (x) sec (x)

sin (θ) = \frac{1}{3}

cos (θ) = 0.9

4 - 4 sin (θ) = 4
