cos(x)= 5/4

Lösung

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

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

Schritte zur Lösung

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

- 1 \leq cos (x) \leq 1

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

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

1 = 2 sin (x)

sin (2 x - \frac{π}{4}) = 0

7 sin^{2} (θ) - 4 sin (θ) = 3

tan (θ) - cot (θ) = 0
