cos(x)=-sqrt(3)

Lösung

cos (x) = - 3

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

Schritte zur Lösung

cos (x) = - 3

- 1 \leq cos (x) \leq 1

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

2 cos (2 x) + 3 cos (x) + 1 = 0

sin (2 x) = - \frac{4}{5}

5 sin (x) - 2 = 0

5 cos^{2} (x) - 2 cos (x) - 3 = sin^{2} (x)

10 cos (θ) = 6
