theta

And then, you would be looking at a piece of that spherical shell corresponding to small values of phi and theta.

然后在这个夹壳中找出一小块，它跟φ和θ有关。

If an anti-Y particle collided with a proton, said proton would turn into a theta particle and a kaon.

如果用一个反”Y“粒子碰撞一个质子，该质子将衰变成一个”θ“粒子和一个K中介子。

So, I cannot ask myself just how will it change if I change theta and do random things with a and b?

因此我无法提问下面这样的问题，如果我改变θ，同时对于a和b做随机的改变，它会怎样变化？

Of course, r goes all around the z axis, but I'm just doing a slice through one of these vertical half planes, fixing the value of theta.

当然，r可以围绕z轴转圈，但我只做了一个垂直的半平面，对于一个确定的θ来说。

So, it is possible to treat -1 as a constant input whose weight, theta, is adjusted in learning, or, to use the technical term, training.

所以，我们可以把-1看成一个常量输入，它的权系数theta在学习（或者用技术术语，称为培训）的过程中进行调整。

Well, let's look at a small piece of our cylinder corresponding to a small angle delta theta and a small height delta z.

考虑圆柱表面的一个小块，它由一个极小的角δθ，和一个极小的高度δz表示。

Well, you could call that the rate of change of theta with respect to theta with a constant.

你可以称之为，保持a不变，θ关于θ自身的变化率。

What you will do is you will look for a given theta what are the bounds of r to be in the region.

你要做的是，在给定θ的情况下，找出这个区域r的上下限是什么。

And, because the equation does not involve theta, it's all the same if I rotate my vertical plane around the z axis.

由于等式没有包含θ，所以可以任意旋转这个垂直平面，绕着z轴。

And of course, if you remember what x and y were in terms of r and theta, you can also keep doing this to figure out, oops.

如果你记得x、y对r、φ的转化方式，就可以继续往下了。

Theta level thought waves were combined with Pranic Chi energy and integrated and amplified into a unique crystalline 'manifestation' wave.

西塔水平的思想波结合普拉那—气—的能量，综合并扩大而成为独特的水晶「显化」波。

And so you can express derivatives either in terms of x, y or in terms of r and theta with simple relations between them.

表示它的微分，要么用x和y，要么用r和θ，它们之间有简单的关系。

And, let's say that we want to understand how the area depends on theta.

这是一个关于a，b，θ函数，我们想知道，面积是怎样依赖于θ的。

The goal is to see how things change when I change theta by a little bit.

我们的目标是来看看当我稍微改变θ时将会怎样变化。

Notice that when theta equals - if the object were here-- that you find that the u=mgR potential energy u equals mg R.

注意，当θ，如果物体在这里-，你会发现，势能。

So, we set this to be zero. Theta, well, we are very happy because we want to express things in terms of theta.

所以我们令它等于零，很好，我们很高兴，因为我们就是想用θ来表示。

The next states, theta brainwaves, are typically of even greater amplitude and slower frequency.

下一个状态时θ脑电波，代表更大的振幅和更小的频率。

OK, and the corresponding angle is going to be measured by theta.

对应的角度是由θ决定的。

Let's start with a simple example of an incline at an angle theta.

让我们以一个角度为，θ的斜坡为例。

And this is always the same, independent of the angle of theta, because gravity is a conservative force.

它一直相同，和角度θ无关，因为重力是常量。
