Question

Calcule o valor da expressão (sen 3π/2 - sen 2π/3)/(3.sen π/6) *


1

-2 - √3 / 3

√6/2

-1 - √3 / 4​

Answer 1

Resposta:

$\frac{sen.\frac{3\pi }{2}-sen.\frac{2\pi }{3} }{3.sen.\frac{\pi }{6} }$

$\frac{-1-\frac{\sqrt{3} }{2} }{3.\frac{1}{2} }$

$\frac{\frac{-2-\sqrt{3} }{2} }{\frac{3}{2} }$

$\frac{-2-\sqrt{3} }{2}.\frac{2}{3}$

$\frac{-2-\sqrt{3} }{3}$
