1. The problem is to simplify the expression $\sec x - 4 \csc x \cdot bc$ or evaluate it if values for $b$ and $c$ are given. 2. Recall the definitions: - $\sec x = \frac{1}{\cos x}$ - $\csc x = \frac{1}{\sin x}$ 3. The expression is $\sec x - 4 \csc x \cdot bc = \frac{1}{\cos x} - 4 \cdot \frac{1}{\sin x} \cdot b c$. 4. Without specific values for $b$, $c$, and $x$, this is the simplified form. 5. If values are provided, substitute and calculate accordingly. This completes part d of problem 1 as requested.
