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 … WebTRIGONOMETRIC IDENTITIES. A N IDENTITY IS AN EQUALITY that is true for any value of the variable. (An equation is an equality that is true only for certain values of the variable.) ( x + 5) ( x − 5) = x2 − 25. The significance of an identity is that, in calculation, we may replace either member with the other.
