arctan(x)=-pi/2

Lösung

arctan (x) = - \frac{π}{2}

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

Schritte zur Lösung

arctan (x) = - \frac{π}{2}

- \frac{π}{2} < arctan (x) < \frac{π}{2}

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

sec^{2} (x) = 1 + tan (x)

csc^{2} (θ) - 2 cot (θ) = 0

cos (θ) = 0.3, 0 \leq θ \leq 2 π

cos (3 x) = - \frac{2}{2}

2 cos (x) + 1 = 2
