Question

resolva as equações para 0 ≤ x < 2π. a)tg x = √3 b) tg x = √3/3 c) tg x = - √3 d) tg x = - √3/3​

Answer 1

a)tg x = √3

x'=60° ==> x"=180+60 = 240°

b) tg x = √3/3

x'=30° ==> x"= 180+30 = 210°

c) tg x = - √3

x'= 180-60=120° ==> x"=360-60 = 300°

d) tg x = - √3/3

x'= 180-30=150° ==> x"=360-30 = 330°
