There's just a equals B, that single thing.
就只有A等于B,那一个东西。
But, we have the constraint, a equals b cosine theta.
但是我们有约束条件,a=b*cosθ
On the other hand, actually, even worse: this thing might not even be well defined. Because if the width of a equals the height of b, we can do this product.
再者说,更糟糕的是:,这个东西甚至不能很好地下定义,因为,如果A的宽和B的高相等,我们可以这样乘。
There's just A equals B, that single thing.
就只有A等于B,那一个东西
pV=RT p plus a over v bar squared times v bar minus b equals r t. All right if you take a equal to zero, these are the two parameters, a and b. If you take those two equal to zero you have p v is equal to r t.
我们就回到,也就是理想气体,状态方程,下面我们来看看,这个方程。
This will generalize to probability of A and B and C equals the probability of A times the probability of B times the probability of C and so on.
简单的说,A和B和C同时发生的概率,等于A发生的概率乘以B发生的概率,乘以C发生的概率,以此类推
