W - Y - A - T - T，好，我没听过这个名字，可以请稍候吗，我去帮你查查看。

x Well, we know how to compute partial w over partial x y or partial w over partial y, which measure how w changes if I move in the direction of the x axis or in the direction of the y axis.

我们知道如何计算∂w/∂,或者∂w/∂,这衡量了我在x轴,或者y轴方向上移动时，w的变化。

So, just to get you used to this idea, I'm going to draw a level surface of a function of three variables OK, so it's a surface given by the equation w of x, y, z equals some constant c.

为了令你们习惯于这个想法，我画一个三变量函数的等值面,这是一个平面,由函数w=c给出的。
