可能性一
瘋狂呃post
再自行刪post
瘋狂加分（猜測）

可能性二
Hack了你的論壇
再自行修改（猜測）

唔係ｇａ～～只要你成日都留喺個論壇，每當你ｒｅｆｌａｓｈ一次就會加１－３分．．．我都唔知點解，所以搞到我發表得十幾，不過有４百幾積分～～～[E-TeH][E-TeH][E-TeH]（爆炸逃．．．．．．．．．）

如果你懂得做的話，恭喜你，你已有form5理科生的程序了~因此這題要用Indefinite Integral

Sorry, I don't think I know how to do it. I haven't learned it yet. (I am only an form 4 arts student.) Oscar, why don't you apply to be the moderator of  功課疑難區 too? You are form 2 only and you are already tackling form 5 maths question! I am sure that you can help us alot in maths.

y=1係錯。
大家留意，我要的是Tangent(A line that has only a point of intersection with another equation=Tangent，不是Trigonomentry的Tangent!)，不是Point。
