My surface is given by the graph of a function.

我们的曲面是由一个函数图像给出的。

And, I have the graph of my function — and I'm asking myself how quickly does the value change when I move on the graph in that direction?

有这样的函数图像-，当沿着图像上的这个方向变化时，试问函数值变化的有多快？

One way to think about it, if you're really still attached to the idea of double integral as a volume what this measures is the volume below the graph of a function one.

一种考虑这个问题的办法是，如果你还觉得，二重积分是求体积的话，那这个度量的，就是函数1的图形下的体积。

Which gets me back to my original point: If you are doing a good job building and maintaining your following on Facebook, and you keep the interesting content flowing, the expansion of the Graph Search function should naturally start to present your business when the search keywords and phrases apply to what you sell.

Quantum annealing is a mathematical operation where the extreme points of a function (the maxima and minma of a graph, for example) are determined from a given set of discrete candidate solutions.
