beweisen cot(θ)=(cos(θ))/(sin(θ))

Lösung

beweisen

cot (θ) = \frac{cos ( θ )}{sin ( θ )}

Wahr

Schritte zur Lösung

cot (θ) = \frac{cos ( θ )}{sin ( θ )}

Verwende die grundlegende trigonometrische Identität:

cot (x) = \frac{cos ( x )}{sin ( x )}

\Rightarrow Wahr

p ro v e (1 - cot (x))^{2} = csc^{2} (x) - 2 cot (x)

p ro v e \frac{1}{cot ( x ) ( 1 - cos ( 2 x ) )} = csc (2 x)

p ro v e (tan (θ) + cot (θ)) cos (θ) = csc (θ)

p ro v e cos^{4} (t) - sin^{4} (t) = 1 - 2 sin^{2} (t)

p ro v e 1 + tan^{2} (- θ) = sec^{2} (θ)
