In this video, we solve a challenging problem from the Singapore Mathematical Olympiad (SMO) 2024 Open Section, Round 1. The problem asks to find the minimum value of the function \( f(x) = \sqrt{x^2 + 1} + \sqrt{(4-x)^2 + 4} \). We employ the triangle inequality and geometric interpretation to determine the solution.
Join us as we break down the steps:
1. Define key points and distances.
2. Apply the triangle inequality.
3. Solve for equality conditions.
4. Find the minimum value of \( f(x) \).
This video is ideal for students preparing for math competitions, particularly those participating in the SMO. Watch and learn how to approach and solve complex mathematical problems efficiently.
