cos (a) = \frac{5}{4}

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

Schritte zur Lösung

cos (a) = \frac{5}{4}

- 1 \leq cos (x) \leq 1

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

1 - 2 sin^{2} (x) = \frac{1}{2}

2 cos (2 θ + 1 0^{\circ}) = 1

cot (β) = \frac{- 3}{3}

2 sin^{2} (3 x) - 3 cos (3 x) + 1 = 0

sin (θ) = \frac{15}{23}
