Wende die Eigenschaften der Trigonometrie an

cos (b) = \frac{19}{35}

Allgemeine Lösung für

cos (b) = \frac{19}{35}

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

b = arccos (\frac{19}{35}) + 2 πn, b = 2 π - arccos (\frac{19}{35}) + 2 πn

b = arccos (\frac{19}{35}) + 2 πn, b = 2 π - arccos (\frac{19}{35}) + 2 πn

3sin(x)-4sin^3(x)=1-2sin^2(x)

3 sin (x) - 4 sin^{3} (x) = 1 - 2 sin^{2} (x)

sin^2(a)=((2tan(a)))/((1+tan^2(a)))

sin^{2} (a) = \frac{( 2 tan ( a ) )}{( 1 + tan ^{2} ( a ) )}

(tan(a))/2 = 2/11

\frac{tan ( a )}{2} = \frac{2}{11}

sin^2(x)-cos(x)= 1/2

sin^{2} (x) - cos (x) = \frac{1}{2}
