Ответ:

Объяснение:

Cos² 2x+ sin² 2x = 1

Answer 2

The expression you've provided is a trigonometric identity. Using the Pythagorean trigonometric identity, we can simplify it:

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

This identity holds true for all values of x. It's a fundamental trigonometric identity that states that the square of the cosine of an angle plus the square of the sine of the same angle is always equal to 1.
