In this video, we solve an important **initial value problem using the Forward Euler Method** step-by-step.

We are given:
dy/dx = 1 + x + y, with y(0) = 1
Step size: h = 0.1
We need to find **y(0.3)** using Euler’s method.

💡 What you'll learn:
- Applying **Euler’s Method iteratively**
- Step-by-step calculation for multiple intervals
- How to handle **recursive updates**
- Exam-focused approach for faster solving ⏱️

🧠 Step-wise Solution:
- Step 1 (x = 0 → 0.1): y₁ = 1.2
- Step 2 (x = 0.1 → 0.2): y₂ = 1.43
- Step 3 (x = 0.2 → 0.3): y₃ = **1.693**

📊 Final Answer:
**y(0.3) ≈ 1.693**
