塞西尔,你又难倒我了。
I was lucking to be an okay jock in hockey, as captain and leading scorer of the high school team, but in college my lack of speed got me again. I had to give it up.
幸好在曲棍球上挽回点颜面,我是高年级队的队长和得分主力,但是到了大学,速度慢又制约了我,我不得不连曲棍球也放弃。
Do you see how we got that? OK, let me do it again.
了解是怎么做了的吗?,好的,我们再来一次。
All right. I want to do one more extended example here., because we've got another piece to do, but I want to capture this, because it's important, so let me again try and say it the following way.
很好的问题,谢谢你,我还要带大家去看一个延伸的例子,尽管我们还有别的事情要去做,但是我还是想提提这一点,因为这很重要。
Now, just to repeat, again I know I've got some math phobics in the audience, let me just slow down a second, all I'm doing here is I'm saying look at this equation of the pink line, look at this equation of the blue line, X is when they cross, i.e., they are equal to each other.
我再重复一遍,我知道你们之中有些人数学不怎么好,我放慢一点说,我是这么解的,看这条粉线的方程,还有这条蓝线的方程,X是二者的交点,也就是说这点两个方程相等
