At April 30, I took over maintenance of of Debian's kFreeBSD autobuilders. Means getting something like 4,5k e-Mails this month (gladly no need to sign all those 4k successful builds any more!), filling nearly 30 RC Bugs (quite a lot of which... | |
# What is the tension on the line when the elevator is accelerating

An elevator weighs 10000N. What is the tension on the line when the elevator is accelerating upwards at 3 m/s?
2. Mar 21, 2006
Well, acceleration is in $\frac {m}{s^2} [/tex]. Is that a typo? Also, what is newtons fir... | |

# Let $f,g: X \rightarrow Y$ be continuous and $Y$ be Hausdorff. Prove that $\{x | f(x) = g(x)\}$ is a closed subset of $X$.
I realize this question has been asked, But i just wrote up this proof and it's a little different so I was hoping somebody would check it.

# Thread: Trouble with integrating trig functions
1. ## Trouble with integrating trig functions
I have two trig functions that i cannot seem to find a way to integrate. They are:
INTEGRAL of: 31(1+cos(x))^2
This one looks pretty simple but whenever i check my answer my taking the derivative of it, it never comes out... | |
## Happy (late) October 1st
China just had their national day (called GuoQinJie I’m told) on October 1st. It was their 60th anniversary so there was a pretty big parade. Which is actually a bit frustrating since I was in Tienanmen Square last October 1st and there was nothing but a bunch of tourists milling around (th... | |
# Some basic derivative-integral issues

### Robokapp
It's not really homework, although that is where I encountered this first time.
I had to evaluate the integral from zero to whatever of 3^x.
I realized...while dy/dx of e^x=e^x the dy/dx of any number not equal to e does not follow the same patter... | |

Definition:Minimal Arithmetic
Minimal arithmetic is the set $Q$ of theorems of the recursive set of sentences in the language of arithmetic containing exactly:
$(\text M 1)$ $:$ $\ds \forall x:$ $\ds \map s x \ne 0$ $(\text M 2)$ $:$ $\ds \forall x, y:$ $\ds \map s x = \map s y \implies x = y$ $(\text M 3)$ $:$ $\ds ... | |
# Local Langlands correspondence and Galois equivariance
The local Langlands correspondence $\text{rec}$ for $\text{GL}_{n}$ itself is not Galois equivariant (i.e. invariant under automorphisms of its field of definition) but rather its twist by contragradient and an unramified character is. In Carayol's article "Non-... | |
## Potential elastic energy problem in an incline
Question
A $$20.0$$ kg package is released on a $$50 ^\circ$$ incline, $$4.50 m$$ from a long spring with force constant $$150$$ N/m that is attached at the bottom of the incline. The block hits the spring, compresses the spring, and finally bounds back. The coefficien... | |

# Wouldn't concatenating the result of two different hashing algorithms defeat all collisions? [duplicate]
Let's say I have three messages: A B C
And I run each of these through two different Hashing algorithms: MD5 and SHA1 for this example
MD5(A) = X
MD5(B) = Y
MD5(C) = Y
SHA1(A) = N
SHA1(B) = N
SHA1(C) = M
