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.

  • Solve for the values in the found out the trigonometric function. 

  • Solve for a required angle.

  • Solve for the values of the variables.

  • If the question specifies any restrictions, apply those restrictions.

Students are advised and recommended to solve more examples to achieve a good level of understanding of the topics.
