sin^2(x)=((9m-9))/7

Lösung

sin^{2} (x) = \frac{( 9 m - 9 )}{7}

Lösung

x = arcsin (\frac{9 m - 9}{7}) + 2 πn, x = π + arcsin (- \frac{9 m - 9}{7}) + 2 πn, x = arcsin (- \frac{9 m - 9}{7}) + 2 πn, x = π + arcsin (\frac{9 m - 9}{7}) + 2 πn

Schritte zur Lösung

sin^{2} (x) = \frac{( 9 m - 9 )}{7}

Löse mit Substitution

sin^{2} (x) = \frac{9 m - 9}{7}

Angenommen:

sin (x) = u

u^{2} = \frac{9 m - 9}{7}

u^{2} = \frac{9 m - 9}{7} : u = \frac{9 m - 9}{7}, u = - \frac{9 m - 9}{7}

u^{2} = \frac{9 m - 9}{7}

Für

x^{2} = f (a)

sind die Lösungen

x = f (a), - f (a)

u = \frac{9 m - 9}{7}, u = - \frac{9 m - 9}{7}

Setze in

u = sin (x)

ein

sin (x) = \frac{9 m - 9}{7}, sin (x) = - \frac{9 m - 9}{7}

sin (x) = \frac{9 m - 9}{7}, sin (x) = - \frac{9 m - 9}{7}

sin (x) = \frac{9 m - 9}{7} : x = arcsin (\frac{9 m - 9}{7}) + 2 πn, x = π + arcsin (- \frac{9 m - 9}{7}) + 2 πn

sin (x) = \frac{9 m - 9}{7}

Wende die Eigenschaften der Trigonometrie an

sin (x) = \frac{9 m - 9}{7}

Allgemeine Lösung für

sin (x) = \frac{9 m - 9}{7}

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π + arcsin (a) + 2 πn

x = arcsin (\frac{9 m - 9}{7}) + 2 πn, x = π + arcsin (- \frac{9 m - 9}{7}) + 2 πn

x = arcsin (\frac{9 m - 9}{7}) + 2 πn, x = π + arcsin (- \frac{9 m - 9}{7}) + 2 πn

sin (x) = - \frac{9 m - 9}{7} : x = arcsin (- \frac{9 m - 9}{7}) + 2 πn, x = π + arcsin (\frac{9 m - 9}{7}) + 2 πn
