What are the Trigonometric Identities?

In trigonometry, the three main important functions are sine, cosine, and tangent. The trigonometric identities are defined as the equation that holds true for the right-angled triangle. These identities are extremely useful when the trigonometric functions need to be simplified. It is mostly used in architecture, which helps to determine the amount of the materials required to construct a building.

Standard Trigonometric Identities

The list of basic trigonometric identities are given below:

  • Tan θ = sin θ / cos θ
  • Csc θ = 1/ sin θ
  • Sec θ = 1/ cos θ
  • Cot θ = cos θ / sin θ
  • Sin2 θ + cos2 θ = 1
  • Sin (- θ ) = – sin θ
  • Cos (-θ) = cos θ
  • Tan (-θ) = – tan θ
  • Sin 2θ = 2sinθ cos θ
  • Cos 2θ = 1- 2 sin2 θ

Frequently Asked Questions on Trigonometric Identities


What are the three basic functions in Trigonometry?

The three essential functions in trigonometry are sine, cosine, and tangent. The other three functions are cosecant, secant, and tangent, which are derived from the basic functions
