One is I keep a constant, and then of course b will have to change because if this width stays the same, then when I change theta, the height increases, and then this side length increases.
一个是我保持a恒定,那么当然b就会变化，因为这个宽是不变的。,那么当改变θ角时，高度增加了，从而这条边的长度增加了。
OK, so if I change theta a little bit in this one, if I change theta a little bit and I keep a the same, then b has to change also in some way.
如果我在这里稍微改变θ的话，如果我稍微改变θ，同时a保持不变，那么b也会在某种程度上变化。
It changes in whatever way it has to change so that when theta changes, a stays the same while b changes so that we keep a right triangle.
它按着既定的方式改变,因此当θ改变时，a保持不变，同时b改变,从而我们保持为直角三角形。
