The second identity. using the above pythagorean identity, we can obtain 2 more pythagorean identities. let us see how we can obtain them. as we know, fundamental pythagorean identity is given by: cos 2 θ sin 2 θ = 1. dividing both sides of the equation by cos 2 θ, we get => cos 2 θ cos 2 θ sin 2 θ cos 2 θ = 1 cos 2 θ. Pythagorean trigonometric identity. Pythagorean trig identities. all pythagorean trig identities are mentioned below together. each of them can be written in different forms by algebraic operations. i.e., each pythagorean identity can be written in 3 forms as follows: sin 2 θ cos 2 θ = 1 ⇒ 1 sin 2 θ = cos 2 θ ⇒ 1 cos 2 θ = sin 2 θ.
