Question

ME AJUDEM POR FAVOR GENTE tou dando 5 estrelas ​

Answer 1

Resposta:

Explicação passo-a-passo:

a)

cotg5π/3 = cotg5.180/3 =

cotg300 = cos300/sen300=(1/2)/(-√3/2)= -1/√3 = -√3/3

b)

cossec5π/6 = cossec5.180/6

cossec150 = -1/sen150 = -1/(1/2) = -2

c)

sec4π/3 = sec4.180/3 = sec240  

1/cos240 = -1/2

d)

cotg 150 = cos150/sen150 = (-√3/2)/(1/2) = -√3

e)

cossec120 = 1/sen120  = 1/(√3/2) = 2/√3 = 2√3/3

f)

sec120 = 1/cos120  = 1/(-1/2) = -2
