(Exercise 10.4 – 1st Year Mathematics | Punjab Board)

Alhamdulillah! In today’s lecture of 1st Year Mathematics, we continued Chapter #10 (Trigonometric Identities) – Exercise 10.4. This lecture is very important because it includes the complete and detailed solution of Question #5 (All Parts) and Question #6, which are highly important from the board exam point of view.

🔹 First, we solved Question #5 (All Three Parts) thoroughly. Each part was discussed with clear logic, showing how to apply Product-to-Sum and Sum-to-Product identities to simplify and transform trigonometric expressions.
🔹 After that, we moved on to Question #6, which is also an important long question. It was explained step by step, focusing on conceptual clarity and exam-oriented methods to make the solution easy to understand and remember.
🔹 Every step was explained with proper reasoning so students can confidently attempt similar questions in their board exams.

✨ With this lecture, students will be able to handle long questions involving trigonometric transformations with confidence and accuracy.

📘 This lecture will help students in:
✅ Solving Exercise 10.4 – Question #5 (All Parts) and Question #6 completely
✅ Understanding the Product-to-Sum and Sum-to-Product applications in depth
✅ Strengthening conceptual understanding of trigonometric identities
✅ Preparing for important long questions for board exams
