Notice how the TouchPad picks up zero fingers, as well as the X and Y coordinate readings when pressing two fingers at widely varying spaces.
在使用不同的距离按两根手指时，请注意TouchPad如何获得零触点以及X和Y坐标读数。
So, at that point, the partial derivative is zero with respect to x.
因此这点上x的偏导为零。
OK, so for a given, x, the range of y is, y 0 It's still zero.
对于给定的x，y的取值范围是。。。,的最小值？，well，，so，what’s，the，lowest，value，of，y，that，we，want，to，look，at？,仍旧是。
The new version of the application is the extremely short line running along the X-axis at zero, while the previous version is the longer higher line.
修改后的应用程序沿着x轴零点的线条非常短，而以前的应用程序的线条则又长又高。
So the signs in the velocity and the signs in average acceleration depend crucially on how I have defined my increasing value of x not where I choose my zero points.
所以速度的符号,和平均加速度的符号,这二者都取决于,这里x正方向,是如何定义的,和0点的选取没有关系。
So, x goes from zero to one. OK, and now, see how in the inner integral, the bounds depend on x.
所以，x的范围是从0到，来看看内积分的积分范围，是怎样取决于x的。
But now it looks like some function of x,y, z equals zero.
但是现在它看起来像x，，y，，z，的函数等于，0。
And the frictional force, in this case will adjust itself just the right way so that Newton's Second Law in the x direction will give you, for the force, a zero.
其它情况下，摩擦力会根据情况调节自身,此时在x方向上使用第二定律,合力为0就是结果。
Well, the reason for that is this corresponds in both cases y It's a rectangle. So, if I slice it this way, 1 you see that y goes from zero to one for any x between zero and two.
原因就是，这对应于对x从0到,从0到1的所有情况。，to，integrating，x，from，zero，to，two，，and，y，from，zero，to，one。,这是一个矩形，这样分割切面，无论x从0到2取哪个值，y的取值都是从0到。
x Xo must be x zero-- - which I conveniently choose zero-- plus 133 meters per second, which is the velocity in the x direction, which never changes.
回到这个点的时候，x，then，when，it，is，back，at，this，point，肯定是-,为了方便我用0表示-,加上133米每秒，这是X方向的速度，它没有变过。
So, let's say that I take a unit square -- -- so, something that goes from zero to one both in x and y directions.
我现在用一个单位正方形——,在x和y方向上都是从0到1变化。
So anyway, this is the origin, and then the last side, y equals zero, x So, somehow, in the change of variables, this square becomes this triangle.
变成另一个点，无论如何，这就是原点，最后一条边，y=0，一直变化，最终变成了v=0，and，x，varies，just，becomes，v，equals，zero。,所以，在变量替换的过程中，这个正方形变成了三角形。
Why is that? Well, let's say that f sub x is zero.
为什么呢？我们令fx为。
It was the apple, x0 and I call that position x zero.
原来是苹果的位置，记作。
x y It's really the same thing. So, x, y, let's see, where is this function equal to zero?
实际上是相同的，函数值为0的点在哪里？
I know v zero x, that is v zero cosine alpha xt=t so x of t is v zero cosine alpha times t but there is no acceleration, so that's it.
并且v0x=v0cosα,那么可有得出,因为没有加速度，所以就是这样了。
Problem 2B is asking you to find the point at which h equals 2200, x=0 partial h over partial x equals zero 0 and partial h over partial y is less than zero.
题2B要求找到一点，在这点处，h等于，且∂h/∂,以及∂h/∂y小于。
Because the probability that two people are the same height is zero, this guarantees that Mr. X will be picked up.
因为两个人的概率是相同的高度是零，这是X先生将拿起保证。
Move with the X axis micrometric movement the sharp shadow, till the digital comparator red light is on the zero right position.
微调移动X轴接近“十”字比较尺，直到数字比较器的指示灯在零点右边变亮。
The limit of the integrand f ( x ) of abnormal integral, which is convergent in the infinite range of integration, is not certainly equal zero at infinity.
摘要无穷限反常积分收敛时，其被积函数在无穷远处的极限不一定为零。
Without a budget constraint, the individual would continues to increase his consumption of X, Y, z,...... until their marginal utilities became zero.
若没有预算约束，个人将不断增加X,Y,Z……的消费，直到它们的边际效用为零。
The zero-valence iron process is a competitive method for treating reactive brilliant orange X-GN wastewater because of its high efficiency and low price.
从以上结果可见，零价铁法处理活性艳橙X-GN染料废水成本低廉，处理效果好，具有很好的应用前景。
An X-tree is a spatial hierarchical tree whose all nodes are 0 except the root node. It is the generalization of the zero tree.
树是除根节点外其余的节点均为0的四叉树，它是零树的一种推广。
An X-tree is a spatial hierarchical tree whose all nodes are 0 except the root node. It is the generalization of the zero tree.
