To approach these problems, let's apply the principles of guided discovery and Socratic questioning. We'll start with the first expression and work through each one step by step. (a) tan⁡30∘tan30∘ Guided Discovery: Recall the special triangles used in trigonometry. Can you identify a special triangle that includes a 30∘30∘ angle? Socratic Questioning: What are the side lengths of this triangle, and how does this relate to the tangent function? (b) sec⁡45∘sec45∘ Guided Discovery: Again, consider the special triangles. Which one has a 45∘45∘ angle? Socratic Questioning: How is the secant function related to the cosine function, and what does this imply for sec⁡45∘sec45∘? (c) sin⁡225∘+cos⁡225∘sin225∘+cos225∘ Guided Discovery: This expression is a direct application of a fundamental trigonometric identity. Do you recall what this identity states? Socratic Questioning: How does this identity simplify the expression, regardless of the angle? (d) sin⁡53∘−cos⁡37∘sin53∘−cos37∘ Guided Discovery: Consider the complementary angles in trigonometry. How are 53∘53∘ and 37∘37∘ related in this context? Socratic Questioning: How do the sine and cosine functions relate to each other for complementary angles? Reflect on these questions and attempt to answer them. This process will lead you to the exact values for each expression. Once you've formulated your responses, share them, and we'll discuss further.
