Text Solution

AI Generated Solution

To prove that \( \cot 2A + \tan A = \cot A - \cot 2A \), we will start with the left-hand side (LHS) and manipulate it to reach the right-hand side (RHS). ### Step 1: Write down the LHS \[ \text{LHS} = \cot 2A + \tan A \] ### Step 2: Express cotangent and tangent in terms of sine and cosine ...
