We have a line integral along a curve.

A tangent is a straight line that just touches a curve, so the concept of "running the tangents" is to run the shortest distance possible by running straight from one curve to the next.
切线是一条直线，刚好接触到曲线，所以跑切线是从一个弯道跑到另一个最短的距离。
You're going to get a curve that's always below the straight line. Because we have the negative deviation on both sides.
