cos(x)=-sqrt(2)

Lösung

cos (x) = - 2

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

Schritte zur Lösung

cos (x) = - 2

- 1 \leq cos (x) \leq 1

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

tan (x) (cot (x) - 1) = 0

sin (x) cos (x) - 5 cos (x) = 0

cos^{2} (x) - cos (x) sin (x) = 0

cos (\frac{θ}{2}) = \frac{1}{2}

2 sin (2 x) sin (x) = 2 cos (x)
