Question

Determins o valor da expressão € raiz de 3. tangente de 300° + sen(pi sobre 2 ) sobre 4. Coseno de 5pi sobre 6​

Answer 1

$\boxed{\begin{array}{l}\sf\sqrt{3}\cdot tg(300^\circ)+\dfrac{sen\bigg(\dfrac{\pi}{2}\bigg)}{4}\cdot cos\bigg(\dfrac{5\pi}{6}\bigg)\\\\\sf\sqrt{3}\cdot(-\sqrt{3})+\dfrac{1}{4}\cdot\bigg(-\dfrac{\sqrt{3}}{2}\bigg)\\\\\sf-3-\dfrac{\sqrt{3}}{8}=-\dfrac{24+\sqrt{3}}{8}\end{array}}$
