AI Generated Solution

To evaluate the given expressions, we will use the properties of complementary angles in trigonometry. ### (i) Evaluate: \( \tan 42^\circ - \cot 48^\circ \) 1. **Identify the relationship between the angles:** We know that \( 42^\circ + 48^\circ = 90^\circ \). Therefore, \( 48^\circ \) is the complement of \( 42^\circ \). 2. **Use the complementary angle identity:** ...
