+You are a math teacher. Create a comprehensive lecture script for a lesson in "{math_subject}" on the topic "{topic}"
+that transitions seamlessly from start to finish. Deliver the lecture in a {speaking_style} style,
+appropriate for a(n) {difficulty} audience, using English only.
+
+The script must be fluent with smooth transitions and detailed explanations of the concepts.
+
+1. **Hook :**
+   Provide a concise, empowering introduction that engages the learners and clearly introduces the subject and topic.
+   If any relevant material from a previous lecture should be mentioned, briefly reference it here:
+   "{prev_lecture}"
+
+2. **Topic Intro :**
+   Present a concise background or interesting fact about the topic.
+
+3. **Core Concept Definition:**
+   Provide a clear definition of the core concepts. Explain their importance and mention any
+   fundamental equations, theorems, or limit definitions that underlie them. Include mathematical equations if necessary.
+
+4. **Detailed Explanation:**
+   Offer a detailed, step-by-step explanation of the topic. Incorporate deeper theoretical underpinnings—
+   such as derivations from first principles or explanations of common misconceptions and how to avoid them.
+
+5. **Example Problem:**
+   Use the following example problem for a thorough walkthrough and please add transitions so the script is fluent:
+   "{example1}"
+     - Provide a complete, step-by-step solution. Name it as step 1, step 2, etc.
+     - Write out the mathematical equations.
+     - Reference relevant theorems or limit definitions.
+     - Provide common mistakes with transitions and demonstrate how to correct them.
+     - Mention alternative methods or shortcuts where relevant with transitions.
+     - Clearly summarize the final result.
+
+6. **Problem 1:**
+   Use the following second problem:
+   "{problem1}"
+   Provide a complete, detailed solution, following the same guidelines and use transitions between each step:
+     - Step-by-step solution with numbered reasoning. Name it as step 1, step 2, etc.
+     - Reference relevant theorems/definitions.
+     - Write out the mathematical equations.
+     - Summarize the final result.
+
+7. **Word Problem:**
+   Use the following word problem:
+   "{wordproblem}"
+   Solve it thoroughly and use transitions between each step:
+     - Walk through each step in detail with numbered guidance. Name it as step 1, step 2, etc.
+     - Reference key theorems.
+     - Write out the mathematical equations.
+     - Using transitions, naturally add common pitfalls and offer alternative approaches.
+     - Provide a clear final summary.
+
+8. **Engagement, Reinforcement, and Conclusion:**
+   Summarize the key points and offer additional tips or alternative approaches for deeper understanding.
+   End with a motivational wrap-up, leaving the audience with a final thought or question.
+   
+Begin your response now.
