This is an informal introduction to some interactions between mathematics and physics, entered around the generalizations of derivatives. 這是一篇關(guān)于數學(xué)和物理中以導數的推廣為中心交流的非正式介紹文章。
Though many parents are uncomfortable with math themselves, experts say informal lessons can be incorporated into everyday activities, such as cooking and driving. 雖然許多家長(cháng)自己對數學(xué)也不大擅長(cháng)，但專(zhuān)家說(shuō)，非正式的課程可以融入每日的活動(dòng)里，像是烹飪或是開(kāi)車(chē)。
