To factor the expression sin^3(x) - cos^3(x), one can use the identity sin^2(x) + cos^2(x) = 1. The expression can be rewritten as (sin(x) - cos(x))(sin^2(x) + sin(x)cos(x) + cos^2(x)). The denominator sin(x) - cos(x) cancels out, leading to the simplified form of sin^2(x) + sin(x)cos(x) + cos^2(x). There is some confusion about whether the result should include a term with sin(x)cos(x). The discussion emphasizes the importance of factoring and using trigonometric identities effectively.
