A problem on my homework:(adsbygoogle = window.adsbygoogle || []).push({});

We learn early on that "the shortest distance between two points is a straight line." Let's prove it...Using the Euler equation, compute the extrema of

∫sqrt(1 + (dy/dx)^{2})dx from x_{1}to x_{2}...show that this corresponds to lines "y = mx +b".

Euler had a lot of different equations. I recognize this as the formula for calculating the length of a graph but that's not what I'm being asked to do. Does anyone what formula this is referring to?

Thanks!
