当然我觉得这本书如果有缺的话，我觉得可能缺了一章比如 “connection between
euclidean geometry, analytic geometry, and algebra, and kinematics”
。。。因为我觉得对很多 spatial thinking 的 kids，建立这三者的概念联系还是
很重要很基础的。。。我在教娃酱油 analytic geometry 基础概念的时候，后来发现

发帖数: 236 | 39 坡度的定义?
坡度是用以表示斜坡的斜度，常用於標記丘陵、屋頂和道路的斜坡坡度。這個數值往往
是以三角函数的正切(tangent)的百分比數值來陳述，即爬升高度比在一個水平面上的
移動距離。除了正切百分比，還會直接標示斜坡垂直提升的角度，甚至會使用正弦(
sine)的百分比數值，即爬升高度比在斜面上的實際(直線)移動距離，這兩個標示法更
常被應用於表示坡度較小的斜坡（少於正切15%）。
坡度標示法的原則都能應用於地形測量學上，雖然使用以上任何一種的標示法都能帶出
同樣的訊息，但為了避免搞亂不精通三角學的讀者，正切百分比還是最常被應用於公共
場所。在英國及香港，正切坡度則常見以比率來取代百分比標示，如1：12取代8.3%。 |
