[Vector]

See that triangle inside of the little pentagon?  It has area 1, and is in proportion p with one of the big triangles (like ACD).

Guess what we started talking about in class today?

Vector, I figured you had a head, but you never told us you have a tail! [/lame joke]

We got another catgirl?..

I do indeed, I do indeed.  You can even multiply me by lambda, if you like!


Vectors: because all that matters in life is magnitude and direction, not position.

What do you get when you cross a mosquito with a mountain climber?

Spoiler (click to show/hide)

You can't cross a vector with a scalar.

[Christes]

You can't!  The mountain climber is a scalar

That's a classic.

(I suppose the mosquito is a vector as well.)

Two more terrible math puns...

What did the blind mathematician say?

See can't

Who built King Arthur's round table?

Oh, the number of places I could take those sentences that would get me kicked off the forums.

One final batch of questions I need a bit of help with, I'm afraid:

Spoiler: one about probability (click to show/hide)

Express in terms of binomial coefficients, the probability of drawing, in a hand of 13 cards:
a.   1 King
b.   2 Queens
c.   an equal number of Kings and Queens

Spoiler: one about limits (click to show/hide)

Find the limit, as n tends to 0, of:
a.   ^sin(x)/_x
b.   ^1-ex/_x

What animal can summate?

The octoplus.

The adder.

Spoiler: one about limits (click to show/hide)

Find the limit, as n tends to 0, of:
a.   ^sin(x)/_x
b.   ^1-ex/_x

L'Hôpital's rule. Whenever you have a limit that equals 0/0 or ±∞/±∞, lim(f(x)/g(x)) = lim(f'(x)/g'(x)).

Spoiler: LIMIT BREAK! (click to show/hide)

lim(x->0)^sin(x)/_x = lim(x->0)^cos(x)/₁ = 1
lim(x->0)^1-ex/_x = lim(x->0)^ex/₁ = 1

Look up permutations and combinations.


EDIT: Also, awesome fractal video.

You can't cross a vector with a scalar.

I love the way you need two completely separate bits of knowledge to make this joke work.

Although I think I'm immune to these now due to my teacher's spontaneous terrible maths puns.  And occasional bizarre questions ("If a student of mass 120kg is lying on a table covered in treacle, and the friction coefficient is 0.5, what angle cam the table be tipped to before he slides off?").

That's the kind of teacher I want to be someday.

30 degrees?  It's been a while.  Either that or 26.6?  Geez, I need to dig my old books out and start going through my past homework.  This is really sad.
