### What are the Trigonometric Equations?

The equations that contain the trigonometric functions of the angles which are unknown are known as the trigonometric equations. The following are the general solutions for some of the trigonometric equations.

General Solutions for the Trigonometric Equations

 Equations General 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] sin 2x = sin 2θ x = nπ ± θ cos 2x = cos 2θ x = nπ ± θ tan 2x = tan 2θ x = nπ ± θ

### How to Solve Trigonometric Equations?

• Find out one function of a single angle.
