Yes, I do know. But I have no time to do such a research work as I am not from R&D department.
Thank you for your advice as I don't think I need somebody to feed on. May be you lack of understanding, it is called "sharing" but not "spoon feeding". Students need to learn sharing among themselves too. You should look up the word "spoon-feed" before you make any command. Anyhow, thanks for your command.
*P.S.Don't worry about my students as I will always let them get flying colours in their results.

当年用它来赶assignment ODE.
可以画2D and 3D graph.

不过,应该不能画sector.

希望帮上你。

多嘴讲几句。。。
赞成jonjon80说的。。应该自己尝试去找。。
以前在念书时候完全没有察觉到什么叫spoon-feed
但是工作后就给老板骂得狗血淋头。。。
虽然那时候很难受,也觉得老板太过分,怎么叫人自己去找嘛!
但是现在。。。觉得受用无穷

一个人,不管做什么,都要自己先去找答案、去想、去尝试
不要总是第一个反应就跟人要答案。。。
这也是我国教育制度跟非填鸭式教育制度的分别。。。
以为只要学生考好成就就行。
其实,学习本来就应该着重于让学生去独立去思考、了解并解决问题
只有去思考,才会发现其中的奥妙,
才会有由衷的喜欢该科目,然后去发掘更多
这么一来,吸取知识的过程才会变得有趣,生动又活泼
