Now we plug this into what we had before, f and that will give us our function f.
把它代入先前我们得到的，我们就会得到函数。
You know it's a gradient, f and you know the function, little f.
如果知道一个梯度，相应地就有一个函数。
Let's think about the tangent plane with regard to a function f.
我们来考虑，关于函数f的一个切平面。
Say that f, our vector field is actually the gradient of some function.
也就是向量场f实际上是一个函数的梯度。
By using the -f option, you tell the tool to emit the function name.
通过使用- f选项，可以告诉工具输出函数名。
The unknown function F can be easily identified like the identification of Lagrange multipliers.
而待定函数F的识别类似于拉氏乘子的识别。
