cos(x)=-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

cos (x) + sin (x) = 1

2 sin (x) = - 2

so l v e f or x, y = sin (x)

3 sec (x) = 2

cot (x) = 2
