的梯度是∂g/∂x,The,gradient,of,g,--,Well,partial,g,,partial,x,那就是-∂f/∂ - Otherwise, I'm going to get a new guess by taking g, x over g, adding them, 2 and dividing by two.

链式法则仅仅是如何对链式函数求导的意思,函数x() 引用函数g() ,你要求导x(g()) 。 - Otherwise, I'm going to get a new guess by taking g, x over g, adding them, 2 and dividing by two.
或者呢,我会有一个关于g的新猜想,就是X大于g,将二者相加,然后除以。

我会从一个猜想开始,把它叫做g,然后我会说,如果g的平方接近于X,打住。
麻省理工公开课 - 计算机科学及编程导论课程节选 - For example, suppose you use vertical motion and you use y instead of x; and a would be g or -g; that's a particle falling down under the affect of gravity.
例如,假设在竖直运动中,你用 y 来代替 x,那么 a 就是 g 或者 -g,这就是一个受重力作用下落的质点
