The static performance of EP-EPS cushioning packaging materials renders non-linear curve, the basic shape is similar to the tangentcurve.
EP - EPS缓冲包装材料的静态性能呈现非线性曲线的特性,基本形状与正切曲线相类似。

Then actually there are ways you can use basically differentials and constrained partials to figure out what the tangent vector to the curve is and so on.
然后,可以用微分关系,或受约束的偏微分来表示,曲线的切向量,就是这样了。

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.
