**Proof of Trigonometric Identity:****Problem Statement:**Prove the identity:\[ \cos x \sin (x + y) - \sin x \cos (x + y) = \sin y \]**Instructions:**Note that each statement must be based on a rule chosen from the Rule menu. For detailed descriptions of each rule, select the information button to the right of the rule.**Interface Explanation:**- **Statement Input:** Here, you input the left-hand side of the identity you’re trying to prove: \[ \cos x \sin (x + y) - \sin x \cos (x + y) \] Below the given statement, there is an input box where you place your simplified statement. This box is currently empty, as shown by the □ symbol.- **Rule Selection:** There is a section titled "Rule" next to the statement input. Clicking on "Select Rule" lets you choose from several trigonometric identities, such as: - Basic trigonometric functions (cosine, sine, tangent) - Reciprocal trigonometric functions (cotangent, secant, cosecant) - Special symbols like π (pi) and the square root symbol Use these rules to help simplify the left-hand side into the right-hand side of the equation.**Validation:**Once the appropriate rule is selected and applied, ensure to validate your step by clicking the "Validate" button.**Graphical Explanation:**- **Rule Options:** There is a visual representation of different trigonometric functions and symbols you can select to apply the corresponding rule. These include tick boxes next to: - Basic Trigonometric Functions (cos, sin, tan) - Reciprocal Trigonometric Functions (cot, sec, csc) - Special mathematical constants and functions (π, square root) - **Navigation Tools:** There are also options to undo steps and seek more info via the question mark icon.**Key Objective:**To prove the given trigonometric identity by systematically applying trigonometric rules and validating each simplification step until the right-hand side equals \(\sin y\).
