To solve the equation \( 2\sin\left(\frac{A}{2}\right) = \sqrt{1 + \sin A} - \sqrt{1 - \sin A} \), we will follow these steps: ### Step 1: Simplify the Right Side Start by simplifying the right-hand side of the equation. We know that: \[ \sqrt{1 + \sin A} - \sqrt{1 - \sin A} \] We can use the identity \( \sin A = 2\sin\left(\frac{A}{2}\right)\cos\left(\frac{A}{2}\right) \) to express \( \sin A \) in terms of \( \sin\left(\frac{A}{2}\right) \) and \( \cos\left(\frac{A}{2}\right) \). ...
