cos(θ)=(2pi)/3

Lösung

cos (θ) = \frac{2 π}{3}

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

Schritte zur Lösung

cos (θ) = \frac{2 π}{3}

- 1 \leq cos (x) \leq 1

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

3 (tan (θ) - 2) = 2 tan (- 7)

4 cos^{2} (x) + 7 cos (x) = 2

sin (x) - 2 cos (x) sin (x) = 0

\frac{3}{5} = cos (x)

tan (θ) = \frac{36}{20 + 16}
