verificar sqrt(1+sin(2x))=sqrt(2)cos(x-45)

Solución

verificar

1 + sin (2 x) = 2 cos (x - 4 5^{\circ})

Falso

Pasos de solución

1 + sin (2 x) = 2 cos (x - 4 5^{\circ})

Ambos lados no son iguales

\Rightarrow Falso

sin^{2} (x) cos^{2} (x) = \frac{1}{4} sin^{2} (2 x)

cos^{3} (θ) + sin^{2} (θ) cos (θ) = cos (θ)

cot^{2} (a) = cos^{2} (a) + ((cot (a)) (cos (a)))^{2}

(1 - sin^{2} (t)) (1 + tan^{2} (t)) = 1

1 - cosh^{2} (x) = - sinh^{2} (x)
