这也就是期望价值理论 expected value theory ; EV
你现在开的车很旧顶多也就值个千把块钱。
顶多也就值上五百法郎!
他们提供的大多数美术作品都比其他画廊的价格要低,他们卖出的最贵一幅壁画也就值5千美元。
Most of the artwork they offer is priced lower than at many galleries; the most expensive piece they've sold was a $5,000 mural.
You know when you add 2 polar forms, you add the radii together, you don't add the angles together, you need to do it in Cartesian form.
表示形式的不同理解,返回给你了不同的值,这也就带来了一系列的问题,第二个问题是。
So, let's say we start off at the distance being ten angstroms. We can plug that into this differential equation that we'll have and solve it and what we find out is that r actually goes to zero at a time that's equal to 10 to the negative 10 seconds.
也就大约是这么多,所以我们取初始值10埃,我们把它代入到,这个微分方程解它,可以发现,r在10的,负10次方秒内就衰减到零了。
Now, the one that we're most interested in ANS is the one where, in fact, it gets out ANS, so you see down here in the code, there's a spot where it's going to return the value of ANS, which is what we want, right? That's the thing that holds the value that we intended to have.
现在我们最感兴趣的是这个,事实上它返回的是,所以你看这段代码,在这里返回ANS值,也就是我们想要的,对吧?,它就承载了我们想得到的值。
