Trigonometric Identitiesis an interesting and important concept that help students to solve trigonometry and geometry problems and understand various mathematical properties. In Maths, an “identity” is an equation that is always true. Similarly, a trigonometric identity is a trigonometric equation that ...
Here are some important trigonometric identities: Reciprocal Identities: Reciprocal identities express the reciprocal trigonometric functions in terms of their counterparts. These identities are useful for converting between trigonometric functions: csc(theta) = 1/sin(theta) sec(theta) = 1/cos(theta) ...

Important Notes on Trigonometric Equations For any real numbers x and y, sin x = sin y implies x = nπ + (-1)ny, where n ∈ Z. For any real numbers x and y, cos x = cos y implies x = 2nπ ± y, where n ∈ Z.
The Pythagorean theorem may be expressed as: sin2(θ) + cos2(θ)=1 As an arclength of 2π corresponds to a full revolution of the circle, sin(θ + 2π) = sin(θ) cos(θ + 2π) = cos(θ)8More identitiessin(−θ) = −sin(θ) cos(−θ) = cos(θ) sin( π 2 −...
