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.

tan (θ/2) = ±√[(1 – cosθ)(1 + cosθ)] Product-Sum Trigonometric Identities The product-sum trigonometric identities change the sum or difference of sines or cosines into a product of sines and cosines.

`cot^2A((secA - 1)/(1 + sinA)) + sec^2A((sinA - 1)/(1 + secA)) = 0` `(1+ cos theta)(1- costheta )(1+cos^2 theta)=1` `(tan theta)/((sec theta -1))+(tan theta)/((sec theta +1)) = 2 sec theta`

If `(tan 3 theta - 1)/(tan 3 theta + 1) = sqrt3`, then the general value of θ is _____. Find the principal solutions of cot θ = 0. The number of principal solutions of tan 2θ = 1 is _____. Prove that the general solution of cos θ = cos α is θ = 2nπ ± α, n ∈ Z.

sec θ = 1/cos θ; cot θ = 1/tan θ; sin θ = 1/cosec θ; cos θ = 1/sec θ; tan θ = 1/cot θ; All these are taken from a right-angled triangle. When the height and base side of the right triangle are known, we can find out the sine, cosine, tangent, secant, cosecant, and cotangent values using trigonometric formulas.

tan(x y) = (tan x tan y) / (1 tan x tan y) sin(2x) = 2 sin x cos x cos(2x) = cos ^2 (x) - sin ^2 (x) = 2 cos ^2 (x) - 1 = 1 - 2 sin ^2 (x) tan(2x) = 2 tan(x) / (1 - tan ^2 (x)) sin ^2 (x) = 1/2 - 1/2 cos(2x) cos ^2 (x) = 1/2 + 1/2 cos(2x)

Take the inverse tangent of both sides of the equation to extract θ θ from inside the tangent. θ = arctan(−1) θ = arctan (- 1) Simplify the right side. Tap for more steps... The tangent function is negative in the second and fourth quadrants.
