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。
I'm going to start with a guess, I'm going to call it g. And then I'm going to say, if g squared is close to x, stop.
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。
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
Then you take the average of g and x over g.
之后你会得到一个大于g的平均数。
