Question

1) (3,0 pontos) Determine o valor do seno, do cosseno e da tangente para os seguintes arcos (utilize duas casas após a virgula): Arco Seno Cosseno Tangente Arco Seno Cosseno Tangente 1377 4050° 6 771 41 4. w/ 1917 -1620° ​

Answer 1

$\large\boxed{\begin{array}{c|l|l|l}\sf arco&\sf seno&\sf cosseno&\sf tangente\\\sf\dfrac{13\pi}{6}&\sf\dfrac{1}{2}&\sf\dfrac{\sqrt{3}}{2}&\sf\dfrac{\sqrt{3}}{3}\\\sf\dfrac{7\pi}{4}&\sf-\dfrac{\sqrt{2}}{2}&\sf\dfrac{\sqrt{2}}{2}&\sf-1\\\sf-1620^\circ&\sf0&\sf-1&\sf0\end{array}}$

$\large\boxed{\begin{array}{c|l|l|l}\sf arco&\sf seno&\sf cosseno&\sf tangente\\\sf4050^\circ&\sf1&\sf0&\sf\not\exists\\\sf\dfrac{4\pi}{3}&\sf-\dfrac{\sqrt{3}}{2}&\sf-\dfrac{1}{2}&\sf-\sqrt{3}\\\sf-\dfrac{19\pi}{3}&\sf-\dfrac{\sqrt{3}}{2}&\sf\dfrac{1}{2}&\sf-\sqrt{3}\end{array}}$
