Question

mim ajudem a resolver, o calculo da cotangente (11rad/6)

Answer 1

Cotangente é calculada por:

$\boxed{Cotg\ x=\frac{cos\ x}{sen\ x}}$

cosseno de 330° = √3/2
seno de 330 = -1/2

$Cotg\ 330\° = \frac{\frac{\sqrt{3}}{2}}{-\frac{1}{2}}\\\\ Cotg\ 330\°=-\frac{2\sqrt{3}}{2}\\\\ \boxed{Cotg\ 330\°=-\sqrt{3}}$
