Allgemeine Lösung für

sec (x) = - \frac{7}{4}

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

x = arcsec (- \frac{7}{4}) + 2 πn, x = - arcsec (- \frac{7}{4}) + 2 πn

x = arcsec (- \frac{7}{4}) + 2 πn, x = - arcsec (- \frac{7}{4}) + 2 πn

28 cos^{2} (θ) = 7

3 - cos (6 x) \cdot 6 = 0

sin (x) - cos (x) = 1, 0 \leq x \leq 36 0^{\circ}

cos (x) = 0, 6
