Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sin(x)^2-sin(y)^2=cos(y)^2-cos(x)^2. section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). Applying the trigonometric identity: \sin\left(\theta \right)^2 = 1-\cos\left(\theta \right)^2. Applying the trigonometric identity: 1-\sin\left(\theta \right)^2 = \cos\left(\theta \right)^2.
