當種植可可豆的非洲農民，第一次嚐到巧克力時的反應，又有趣又辛酸啊～ 


竟然沒吃過自己採了幾十年的東西！

可可是巧克力的原料，相信大家都知道。非洲生產的可可豆約占世界總產量的65%，可是非洲窮苦的採可可工人卻沒機會吃到巧克力，大部分一採下就被美國以期貨的方式買斷了。這次，主持人來到了可可的主要生產國象牙海岸，帶著許多一般商店都有賣的巧克力到那邊請採收可可的工人吃，得出的結果讓人感慨。

第一次吃到巧克力的採收工人們驚為天人，紛紛稱讚巧克力的美味。大部分都不知道他們採收的可可豆到底做什麼去了，有些人聽父母說是拿去釀成酒了，卻不知道巧克力為何物。大家吃完後還熱切討論，「原來白人都吃這個，難怪這麼健康」、「是不是吃了這個皮膚會變白？」、「我要留下包裝紙給我的孩子看」等等，讓人不禁感慨巧克力是這麼平凡的東西，在它原料的原產地的人民卻無法享用這般美食。

巧克力在當地的售價十分昂貴，一條要價2歐元，採收工人的工頭一天努力的工資只有7歐元，這一天7歐元的工資，他與15個家人和4個工人的工資都仰賴著它，所以要買一條巧克力幾乎是不可能的事。生活在平常伸手就能吃到巧克力的地方的我們，一定要懂得惜福！

What is the equation of a 3D cone with generalised tilt?

Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite What is the equation of a 3D cone with generalized tilt? I've noticed that in most equations given to represent a cone, there is no parameter which defines the tilt of the cone in 3D space and that most of them have their point at the origin $(0,0,0)$ - I was wondering if anyone could give me a more generalized cone equation for a cone in any position in 3D space 3d share | cite | improve this question edited Jul 25 '16 at 0:05 ervx 9,425 3 13 36 asked Jul 24 '16 at 15:38 Charlene 11 2 2 Welcome to Math.SE! Could you please explain a few things to help people give an answer useful to you: 1. What do you mean by "generalized tilt"? 2. Are you asking about a right circular cone? Does the angle at the vertex matter? 3. What form of answer (implicit, parametric...?) are you looking for? 4. If this is homework, what tools do you have available, an...

Relationship between determinant of matrix and determinant of adjoint?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite We are studying adjoints in class, and I was curious if there is a relationship between the determinant of matrix A, and the determinant of the adjoint of matrix A? I assume there would be a relationship because finding the adjoint requires creating a cofactor matrix and then transposing it. linear-algebra determinant adjoint-operators share | cite | improve this question asked Nov 17 '17 at 17:32 CluelessCoder 32 5 For a square matrix $A$ of order $n$, we have $A(operatornameadj A)=(operatornameadj A)A=|A|I_n$ where $I_n$ is the identity matrix of order $n$. This should tell you about the determinant of the adjoint in terms of that of $A$ (use multiplicative property and other elementary properties of determinants). – Prasun Biswas Nov 17 '17 at 17:35 1 @CluelessCoder: see here: math.stackexchange.com/questions/516127/…...

Color the edges and diagonals of a regular polygon

Image
Clash Royale CLAN TAG #URR8PPP up vote 5 down vote favorite 1 Here is the problem: For what $n$ is it possible to color the edges and diagonals of an $n$-side regular polygon with $dfracbinomn23$ colors, such that you use every color exactly three times and for every color the three segments (edges or diagonals) with that color form a triangle? Trivially $nequiv 0 text or 1 pmod3$. I can also prove that if the statement is true for $k$ than it is true for $3k$ as well. How to finish? Please help!

Aren't the side of a regular polygon the same as the edges? A regular $n$-sided polygon has $n$ edges. – hardmath Aug 6 at 21:20 3 $n$ ne...
