This step focuses on simplifying the numerator of the expression ( + 2)/(1 + + 2). Step 2: Simplify the numerator of the LHS. The numerator is the top part of the fraction, which is + 2. To simplify this, we use a double angle identity for sine. The identity states that 2 can be rewritten as 2 . This substitution is crucial because it allows us to express both terms in the numerator using and of a single angle , rather than having terms with 2. Substituting 2 = 2 into the numerator gives: + 2 = + 2 Now, we observe that both terms on the right-hand side, and 2 , share a common factor of . To simplify further, we factor out this common term : = (1 + 2 ) When is factored out from , it leaves 1 (since = · 1). When is factored out from 2 , it leaves 2 . This results in the simplified form of the numerator: (1 + 2 ). This factored form is useful because it often allows for cancellation with terms in the denominator, as seen in the full solution.
