Tangent difference identity

WebThe Pythagorean trigonometric identities in trigonometry are derived from the Pythagoras theorem.The following are the 3 Pythagorean trig identities. sin 2 θ + cos 2 θ = 1. This can also be written as 1 - sin 2 θ = cos 2 θ ⇒ 1 - cos 2 θ = sin 2 θ; sec 2 θ - tan 2 θ = 1. This can also be written as sec 2 θ = 1 + tan 2 θ ⇒ sec 2 θ - 1 = tan 2 θ; csc 2 θ - cot 2 θ = 1. WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ.
