Text Solution

AI Generated Solution

To show that \( \tan^{-1} \left(\frac{1}{2}\right) + \tan^{-1} \left(\frac{1}{3}\right) = \tan^{-1} \left(\frac{3}{4}\right) \), we will use the property of inverse tangent functions: \[ \tan^{-1}(A) + \tan^{-1}(B) = \tan^{-1} \left( \frac{A + B}{1 - AB} \right) \] **Step 1: Identify A and B** ...
