Mathematics - 13 September 2006

-Where did this first enter into mathematics and why? Is it possible that they adopted it from philosophy and the negation of the negation / absolute negativity (e.g. Hegel / dialectics)?

Biotechnology failed to deliver what I wanted. Virtually all of the subjects covered didn't involve creativity and problem-solving. Only mindless "cram 100+ pages into your brain, pray that everything stays completely intact and score in exam and forget everything about it the next month" nonesense. And I suppose even if I graduate and get a job it will also not involve much creativity and problem solving.
So I will be taking Mathematics or Mathematical Physics as my second degree and I plan to continue up to PhD level. But are these courses deliver the same old cramming idiocy as the non-mathematical subjects?Do you graduate and work using your problem-solving skills?

square 1: W=2x L=x
square 2: W=x/2 L=x/2
square 3: W=x-5 L=6

i am just double checking on this

i am taking the integral of

(e^-t)<3,t,sint>

so it should be the integral of

3(e^-t)i + t(e^-t)j + (e^-t)(sint)k
right?

and that means the integral of the k part is gonna suck right?

hopefully i missed something.

You are at the center of a 20m equilateral triangle with a raptor at each corner. You can immediately accelerate to your top speed of 6m/s. The raptors can accelerate at 4m/s^2 to their top speed of 25m/s. The top raptor has a wounded leg and is limited to a top speed of 10m/s. The raptors will run towards you. At what angle should you run to maximize the time you stay alive?
