Lösung

beweisen

cos (x^{2}) = \frac{1}{sec ( x ^{2} )}

Wahr

Schritte zur Lösung

cos (x^{2}) = \frac{1}{sec ( x ^{2} )}

Verwende die grundlegende trigonometrische Identität:

cos (x) = \frac{1}{sec ( x )}

\Rightarrow Wahr

p ro v e cot (x) + tan (x) = \frac{2}{sin ( 2 x )}

p ro v e sec (\frac{5 π}{6}) = \frac{- 2}{3}

p ro v e cos (ω) (sec (ω) - cos (ω)) = sin^{2} (ω)

p ro v e \frac{sin ( θ )}{1 + cos ( θ )} + cot (θ) = csc (θ)

p ro v e tan (x) csc (x) = tan (x) sin (x) + cos (x)
