Convert to sine and cosine: \(\tan \theta = \frac{\sin \theta}{\cos \theta}\), \(\cot \theta = \frac{\cos \theta}{\sin \theta}\), \(\sec \theta = \frac{1}{\cos \theta}\), \(\csc \theta = \frac{1}{\sin \theta}\). So expression becomes: \(\frac{\frac{\sin \theta}{\cos \theta} + \frac{\cos \theta}{\sin \theta}}{\frac{1}{\cos \theta} \cdot \frac{1}{\sin \theta}} = \frac{\frac{\sin^2 \theta + \cos^2 \theta}{\sin \theta \cos \theta}}{\frac{1}{\sin \theta \cos \theta}} = \frac{\frac{1}{\sin \theta \cos \theta}}{\frac{1}{\sin \theta \cos \theta}} = 1\).

Break down complex topics into smaller, manageable chunks for easier recall.
