Prove that:`cos^(-1)(12/13)+sin^(-1)(3/5)=sin^(-1)(56/65)`

Explanation

To prove that \( \cos^{-1}\left(\frac{12}{13}\right) + \sin^{-1}\left(\frac{3}{5}\right) = \sin^{-1}\left(\frac{56}{65}\right) \), we will follow these steps:

### Step 1: Define the angles
Let:
- \( A = \cos^{-1}\left(\frac{12}{13}\right) \)
- \( B = \sin^{-1}\left(\frac{3}{5}\right) \)

### Step 2: Find \( \cos A \) and \( \sin B \)
