Question

77. Sejax = pi/6. Determine dos valores de a) sen x
b) cos x
c) tg x
d) cotg x
e) sec x
f) cossec x

Answer 1

Resposta:

a) sen(30°) = 1/2

b) cos(30°) = $\sqrt{3}/2$

c) tg(30°) = $\sqrt{3}/3$

d) cotg(30°) = $\sqrt{3}$

e) sec(30°) = $\frac{2\sqrt{3} }{3}$

f) cossec(30°) = 2

Explicação passo-a-passo:

Primeiramente, $\pi$ =180°.

Logo, $\pi$/6 = 180/6 = 30°

sen(30°) = 1/2

cos(30°) = $\sqrt{3}/2$

tg(30°) = $\sqrt{3}/3$

cotg(30°) = $\sqrt{3}$

sec(30°) = $\frac{2\sqrt{3} }{3}$

cossec(30°) = 2
