cos(x)=9

Lösung

cos (x) = 9

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

Schritte zur Lösung

cos (x) = 9

- 1 \leq cos (x) \leq 1

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

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

sin (x + \frac{π}{2}) - cos (x + \frac{3 π}{2}) = 0

tan (x) = \frac{\frac{3}{2}}{\frac{1}{2}}

tan (2 x) + sec (2 x) = 11

- 8 sin (x) + 8 cos (2 x) = 0
