sec (x) = 3

Allgemeine Lösung für

sec (x) = 3

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

x = arcsec (3) + 2 πn, x = 2 π - arcsec (3) + 2 πn

x = arcsec (3) + 2 πn, x = 2 π - arcsec (3) + 2 πn

cot (θ - 3 0^{\circ}) = \frac{1}{3}

(cot (x) - 3) (csc (x) + 2) = 0

sin (x) = \frac{7}{9.4}

cos (x) = \frac{6}{11}

3 cos^{2} (x) + 5 sin (x) - 1 = 0
