Question

what is a trigonometic equation​

Answer 1

Answer:

Equations Solutions

sin x = 0 x = nπ

cos x = 0 x = (nπ + π/2)

tan x = 0 x = nπ

sin x = 1 x = (2nπ + π/2) = (4n+1)π/2

cos x = 1 x = 2nπ

sin x = sin θ x = nπ + (-1)nθ, where θ ∈ [-π/2, π/2]

cos x = cos θ x = 2nπ ± θ, where θ ∈ (0, π]

tan x = tan θ x = nπ + θ, where θ ∈ (-π/2 , π/2]

sin2 x = sin2 θ x = nπ ± θ

cos2 x = cos2 θ x = nπ ± θ

tan2 x = tan2 θ
