cos(3x)=2

Lösung

cos (3 x) = 2

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

Schritte zur Lösung

cos (3 x) = 2

- 1 \leq cos (x) \leq 1

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

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

8 cos^{2} (x) - 4 = 0

tan (x) = - 5

6 cos^{2} (x) - 3 = 0

sin (x) + sin (3 x) = 0
