Schritte zur Lösung

cos^{2} (x) = \frac{3}{5}

Löse mit Substitution

cos^{2} (x) = \frac{3}{5}

Angenommen:

cos (x) = u

u^{2} = \frac{3}{5}

u^{2} = \frac{3}{5} : u = \frac{3}{5}, u = - \frac{3}{5}

u^{2} = \frac{3}{5}

Für

x^{2} = f (a)

sind die Lösungen

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

u = \frac{3}{5}, u = - \frac{3}{5}

Setze in

u = cos (x)

ein

cos (x) = \frac{3}{5}, cos (x) = - \frac{3}{5}

cos (x) = \frac{3}{5}, cos (x) = - \frac{3}{5}

cos (x) = \frac{3}{5} : x = arccos (\frac{3}{5}) + 2 πn, x = 2 π - arccos (\frac{3}{5}) + 2 πn

cos (x) = \frac{3}{5}

Wende die Eigenschaften der Trigonometrie an

cos (x) = \frac{3}{5}

Allgemeine Lösung für

cos (x) = \frac{3}{5}

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

x = arccos (\frac{3}{5}) + 2 πn, x = 2 π - arccos (\frac{3}{5}) + 2 πn

x = arccos (\frac{3}{5}) + 2 πn, x = 2 π - arccos (\frac{3}{5}) + 2 πn

cos (x) = - \frac{3}{5} : x = arccos (- \frac{3}{5}) + 2 πn, x = - arccos (- \frac{3}{5}) + 2 πn

cos (x) = - \frac{3}{5}

Wende die Eigenschaften der Trigonometrie an

cos (x) = - \frac{3}{5}

Allgemeine Lösung für

cos (x) = - \frac{3}{5}

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

x = arccos (- \frac{3}{5}) + 2 πn, x = - arccos (- \frac{3}{5}) + 2 πn

x = arccos (- \frac{3}{5}) + 2 πn, x = - arccos (- \frac{3}{5}) + 2 πn
