Allgemeine Lösung für

sec (α) = \frac{9}{5}

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

α = arcsec (\frac{9}{5}) + 2 πn, α = 2 π - arcsec (\frac{9}{5}) + 2 πn

α = arcsec (\frac{9}{5}) + 2 πn, α = 2 π - arcsec (\frac{9}{5}) + 2 πn

α = 0.98176 \dots + 2 πn, α = 2 π - 0.98176 \dots + 2 πn

cos^{2} (x) + sin (x) = \frac{5}{4}

\frac{8.87}{9.8} = sin (α) - 0.1 1 - sin^{2} (α)

2 = csc (x) cot (x)

5 cos^{2} (θ) + 32 sin (θ) - \frac{11}{2} = 0

cos^{2} (x) - 5 cos (x) + 2 = 0
