Factor cos(x)

Problem

cos(x)

Solution

1. Identify the expression as a basic trigonometric function.

2. Determine if the expression can be factored using standard algebraic methods such as common factors, difference of squares, or trinomial factoring.

3. Conclude that since cos(x) is a single term and a fundamental trigonometric ratio, it is already in its simplest irreducible form over the real numbers.

Final Answer

cos(x)=cos(x)
