不好意思,J版,我女儿刚回家来。我让她看了您的讲解,她说老师也是这样讲解的,但是同学们还是不能理解 ...
知名补习老师Miss Loi i这样解释 “Hence”这个词:
“If that’s not clear enough, the Hence is meant to remind you to use information from your answer/workings in an earlier part to solve the next part. Sounds easy but sometimes it’s not so straightforward and you’ll usually need to think of one more step before attaining enlightenment.
Differentiation and Integration are a match made in heaven. So unless they are having a tiff, there’s a good chance you’ll see them together in the same question. Miss Loi has observed that many students got so enchanted by the sexy integral sign that they totally forgot about their differentiation techniques, and vice versa for those with more … errmmm … ‘differential’ tastes.
So whenever you spot the word Hence, remember to 看前面 (watch your front again)!!!”
