Question

observe as relações ao lado de cada função e de o valor de:
a) Sec 60°

b) Cotg 30°

c) Csc 60°​

Answer 1

a) Sec 60° = 1/cos60 =1/(1/2) = 2

b) Cotg 30° = 1/tg30 = 1/(√3/3) = √3

c) Csc 60° = 1/sen60= 1/(√3/2)= 2√3/3

Answer 2

cos(60) = 1/2

sec(60) = 1/(1/2) = 2

costg(30) = tg(60) = √3

sen(60) = √3/2

csc(60) = 1/(√3/2) = 2/√3 = 2√3/3
