0° ≤ x ≤ 3π

Tan x = 1/3 √3
Tan x = Tan 30° , Tan 210° , Tan 390°
x = 30° , 210° , 390°

Hp : {30° , 210° , 390°}
Hp : {1/6π , 7/6π , 13/6π}

Answer 2

Verified answer

Tan x = 1/3 akar3
tan x = tan phi/6

x = phi/6 + k.phi
k = 0, x = phi/6
k = 1, x = 7phi/6
k = 2, x = 13phi/6

Hp = {phi/6 , 7phi/6 , 13phi/6}
