x = 26.56505 \dots^{\circ} + 36 0^{\circ} n, x = 153.43494 \dots^{\circ} + 36 0^{\circ} n, x = - 26.56505 \dots^{\circ} + 36 0^{\circ} n, x = 206.56505 \dots^{\circ} + 36 0^{\circ} n

Schritte zur Lösung

sin^{2} (x) = 0.2

Löse mit Substitution

sin^{2} (x) = 0.2

Angenommen:

sin (x) = u

u^{2} = 0.2

u^{2} = 0.2 : u = 0.2, u = - 0.2

u^{2} = 0.2

Für

x^{2} = f (a)

sind die Lösungen

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

u = 0.2, u = - 0.2

Setze in

u = sin (x)

ein

sin (x) = 0.2, sin (x) = - 0.2

sin (x) = 0.2, sin (x) = - 0.2

sin (x) = 0.2 : x = arcsin (0.2) + 2 πn, x = π - arcsin (0.2) + 2 πn

sin (x) = 0.2

Wende die Eigenschaften der Trigonometrie an

sin (x) = 0.2

Allgemeine Lösung für

sin (x) = 0.2

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

x = arcsin (0.2) + 2 πn, x = π - arcsin (0.2) + 2 πn

x = arcsin (0.2) + 2 πn, x = π - arcsin (0.2) + 2 πn

sin (x) = - 0.2 : x = arcsin (- 0.2) + 2 πn, x = π + arcsin (0.2) + 2 πn

sin (x) = - 0.2

Wende die Eigenschaften der Trigonometrie an

sin (x) = - 0.2

Allgemeine Lösung für

sin (x) = - 0.2

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

x = arcsin (- 0.2) + 2 πn, x = π + arcsin (0.2) + 2 πn

x = arcsin (- 0.2) + 2 πn, x = π + arcsin (0.2) + 2 πn
