Question

Resolva as Equações no intervalo 0 menor e igual  x ∠ 2π

a) senx=1
b)cosx=0
c)tgx=1
d)senx= -1/2
e) tgx= 0

Answer 1

0 ≤ x < 2π

a) senx = 1 => x = π/2

b) cosx = 0 => x = π/2 ou x = 3π/2

c) tgx = 1 => x = π/4 ou x = π + π/4 = 5π/4

d) senx = -1/2 => x = π + π/6 = 7π/6 ou x = 2π - π/6 = 11π/6

e) tgx = 0 => x = 0 ou x = π
