t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are.
Example 29 Prove cos2 x + cos2 (x + pi/3) + cos2 (x pi/3)
Explanation: We know that ,cos is an even function. ⇒ cos( −θ) = cosθ. ∴ cos(x − π 2) = cos( π 2 −x) = sinx. OR. cos(A −B) = cosAcosB + sinAsinB. cos(x − π 2) = cosxcos( π 2) + sinxsin( π 2) cos(x − π 2) = cosx(0) +sinx(1) = 0 +sinx = sinx.

Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of.
