Thank you RGV. I will check it.

Let me introduce myself. Sorry to take pity on me. I graduated from Physics and now studying in computer science. Of course, I studied Lagrange multiplier in classical mechanics. I always spend my free time to enjoy mathematics and computing. I found this problem from math.or.th age not over...

Homework Statement Given x+y = 6\sqrt2 a + b = 6\sqrt 2 Find minimum value of \sqrt{x^2 + a^2} + \sqrt{y^2+b^2} 2. The attempt at a solution I had plotted the f(x,y) with constant a ,b And that's all. I don't realize how to do this. Any comment will be appreciated
