Answer 2

The trigonometric identity you've written, "sin^2(x) + cos^2(x) = sin(2x)", is incorrect. The correct trigonometric identity is known as the Pythagorean Identity, which states:

sin^2(x) + cos^2(x) = 1

This identity holds true for all values of x, where sine and cosine are defined. It's one of the fundamental trigonometric identities and is derived from the Pythagorean theorem in a unit circle context.
