We will apply the following more fundamental trigonometric identity $\boxed{\tan^2 x 1 = \sec^2 x}$ The proof is started from the righthand side In the first method, we used the identity \({\sec}^2 \theta={\tan}^2 \theta1\) and continued to simplify In the second method, we split the fraction, putting both terms in the numerator over the common denominator This problem illustrates that there are multiple ways we can verify an identityIdentities tan x = sin x/cos x equation 1 cot x = cos x/sin x equation 2 sec x = 1/cos x equation 3 csc x = 1/sin x equation 4 cot x = 1/tan x equation 5 sin 2 x cos 2 x = 1 equation 6 tan 2 x 1 = sec 2 x equation 7 1 cot 2 x = csc 2 x equation 8 cos (x y) = cos x cos y sin x sin y equation 9 sin (x y) = sin x cos y cos x sin y equation 10 cos (x) = cos x equation 11

TRIGONOMETRIC IDENTITIES Trigonometric identities are equalities where we would have trigonometric functions and they would be true for every value of the occurring variables Geometrically, these are identities involving certain functions of one or more anglesNotice how a "co (something)" trig ratio is always the reciprocal of some "nonco" ratio You can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine The following (particularly the first of the three below) are called "Pythagorean" identities sin 2Trigonometric Identities List There are various identities in trigonometry which are used for many trigonometric problems Let us see all the fundamental trigonometric identities here Reciprocal Identities Sin θ = 1/Csc θ or Csc θ = 1/Sin θ;
