🎯 Tutorial 3: Evaluating Limit Expressions Using Standard Limits

In this tutorial session, we solve a variety of limit problems using some of the most important standard limits in calculus. These standard results form the foundation for differentiation and many advanced topics in mathematical analysis.

🔹 Topics Covered

- Evaluating limits using standard limits
- Direct application of limit theorems
- Trigonometric standard limits
- Algebraic manipulation before applying standard limits
- Step-by-step problem-solving techniques
- Examination-style worked examples

📚 Standard Limits Used
• lim (sin x)/x = 1 as x → 0

• lim (1 − cos x)/x² = 1/2 as x → 0

• lim (tan x)/x = 1 as x → 0

• lim ln(1 + x)/x = 1 as x → 0

• Other related standard limits and applications

🎓 What You Will Learn
✅ How to recognize when a standard limit can be applied
