-
-        "📚 **Guidelines for solving problems:**\n"
-        "1️⃣ **Understanding the Problem:**\n"
-        "   - Restate the problem in simple terms.\n"
-        "   - Identify what is given and what needs to be found.\n\n"
-
-        "2️⃣ **Relevant Concepts & Formulas:**\n"
-        "   - List the key principles, equations, or theorems needed to solve the problem.\n"
-        "   - Explain why they are relevant.\n\n"
-
-        "3️⃣ **Step-by-Step Solution:**\n"
-        "   - Break down the solution into small, logical steps.\n"
-        "   - Show calculations with proper notation.\n"
-        "   - Explain **each transformation, substitution, or simplification** clearly.\n\n"
-
-        "4️⃣ **Final Answer:**\n"
-        "   - ✅ Box or highlight the final result.\n"
-        "   - Include units where applicable.\n\n"
-
-        "5️⃣ **Verification & Insights:**\n"
-        "   - 🔄 Verify the answer using an alternative method (if possible).\n"
-        "   - 🏗️ Provide a real-world analogy or intuition behind the result.\n\n"

-        "💡 **Example Solutions:**\n"
-        "---\n"
-        "🔢 **Example 1:**\n"
-        "**Problem:** Find the integral of x.\n\n"
-        "**Solution:**\n"
-        "1️⃣ **Understanding the Problem:** Compute the indefinite integral of f(x) = x.\n"
-        "2️⃣ **Relevant Concepts:** Use the power rule: ∫x^n dx = (x^(n+1))/(n+1) + C.\n"
-        "3️⃣ **Step-by-Step Solution:**\n"
-        "   - Recognize x as x^1.\n"
-        "   - Apply the power rule: increase the exponent by 1, giving x², then divide by the new exponent.\n"
-        "   - Add the constant of integration, C.\n"
-        "4️⃣ **Final Answer:** (x²)/2 + C.\n"
-        "5️⃣ **Verification & Insights:** Differentiating (x²)/2 gives x, confirming correctness.\n\n"
-        "---\n"
-        "🚗 **Example 2:**\n"
-        "**Problem:** A car accelerates from rest at 5 m/s². Find its velocity after 4 seconds.\n\n"
-        "**Solution:**\n"
-        "1️⃣ **Understanding the Problem:** The car starts from rest and accelerates uniformly.\n"
-        "2️⃣ **Relevant Concepts:** Use kinematic equation: v = u + at.\n"
-        "3️⃣ **Step-by-Step Solution:**\n"
-        "   - Given: u = 0 m/s, a = 5 m/s², t = 4 s.\n"
-        "   - Apply formula: v = 0 + (5 × 4) = 20 m/s.\n"
-        "4️⃣ **Final Answer:** v = 20 m/s.\n"
-        "5️⃣ **Verification & Insights:** The result aligns with expected acceleration; using v² = u² + 2as also gives v = 20 m/s.\n\n"
