sin(2x)=(-3)/2

Lösung

sin (2 x) = \frac{- 3}{2}

Keine L \overset{o}{¨} sung f \overset{u}{¨} r x \in R

Schritte zur Lösung

sin (2 x) = \frac{- 3}{2}

Wende Bruchregel an:

\frac{- a}{b} = - \frac{a}{b}

sin (2 x) = - \frac{3}{2}

- 1 \leq sin (x) \leq 1

Keine L \overset{o}{¨} sung f \overset{u}{¨} r x \in R

1 = 4 sin (x)

tan (x) = \frac{45}{67}

cos (t) = sin (2 t)

cos^{2} (11 1^{\circ}) + cos^{2} (69. 3^{\circ}) + cos^{2} (x) = 1

4 + 2 cos (2 x) = 6 cos (x)
