cos(x)=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

sin (2 θ) = 3 cos (θ)

cos (θ) = - \frac{2}{5}

tan^{2} (θ) - 3 = 0

cos (2 x) + 2 cos (x) = - 1

1 + sin (x) = 2 cos^{2} (x)
