Answer 3

It seems like you're asking for an explanation or solution related to the equation cos(2x) = 1. The equation involves a trigonometric function, cosine, and you're looking for the value(s) of x that satisfy the equation.

The cosine function has a range between -1 and 1. The equation cos(2x) = 1 is satisfied when the cosine of 2x equals 1. This occurs when 2x is an even multiple of π (pi) radians. In other words:

cos(2x) = 1 2x = 2nπ, where n is an integer

Dividing both sides by 2: x = nπ

So, the solutions to the equation cos(2x) = 1 are given by x = nπ, where n is any integer.

If you have a specific value or range for x in mind, please provide more details so I can assist you further.
