arctan(x)=90

Lösung

arctan (x) = 90

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

Schritte zur Lösung

arctan (x) = 90

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

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

cos (5 θ) - cos (7 θ) = 0

sin (x - \frac{π}{3}) = \frac{2}{2}

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

2 cos (\frac{x}{2}) - 2 = 0, 0 \leq x < 2 π

cos (\frac{x}{4}) = - \frac{2}{2}
