No. It would clearly be Vin Diesel.

Re: Amusing answers to tests

I don't know if Batman is the derivitive of Bruce Wayne, but I'll swear in blood that Spiderman is the derivitive of Mary Jane-- You know he lies adjacent to those curves. You fail. Derivatives (yeah, with an 'a') lie tangent to curves. You also fail. The derivative tells yo...

Re: Simple L2 function space question

Yes.

And why isn't a jump discontinuity square integrable?

Re: Irrational indices

What does "principal value" even mean other than the value that the expression is? It's what the series works out to. Saying a number "is an ith power of i" is not the same as saying that a number "is i^i". Only one number is i^i - just like only one number is 1^0.25 e...

Re: Division by Zero (Please, no new threads about this)

Let's not forget that proving the inconsistency of ZFC would not be a setback for mathematics, it would be a breakthrough. Maybe an unwanted breakthrough, but still a breakthrough.

Re: Division by Zero (Please, no new threads about this)

Or you could append infinity, define some of the operations that you want to define and realize that you've left other operations undefined and broken (or put a lot of stress on, depending how you think about things) some of the algebraic properties that you like. http://en.wikipedia.org/wiki/Real_...

Re: so maths is useful for what now?

I'm looking to buy a diamond for my girlfriend. She wants a nine-sided regular polyhedron. You should really consider geting a diamond cut with more facets than 9. It's all the many faces that make the diamond sparkle and shine. One of the more popular cuts is the round brilliant with 58 different ...

Re: Division by Zero (Please, no new threads about this)

The answer to this stupid problem is very simple. Take the real numbers with their common axkoms. Then define a new number called infinity. Lay down another axiom which says that the reciprical of zero is infinity. Then derive a contradiction to show that your set of axioms is inconsistent and every...

Re: ideas for a statistics or math-themed bday cake?

Obviously the best idea is to bake a cake which can be cut into five pieces and reassembled into two cakes the same size as the original.
