cos(2x)=sqrt(3/2)

Lösung

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

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

Schritte zur Lösung

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

- 1 \leq cos (x) \leq 1

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

- 3 cos (2 θ) + 2 sin (θ) + 5 = 9 sin (θ)

3 + sin (x) = 5 cos (2 x)

cos (x) = \frac{15}{20}

a sin (x) + b cos (x) = 0

tan (2 x) = - 0.025
