it's an old one, about a prisoner who is sentenced penal servitude ( labor ) , and has cuffs on legs like the one in the photo , then , with an axe, he breaks them and run away...

later in the movie, he enters a cinema, to find out that the movie (in the cinema ) is about his life and how he broke out ( i think he started crying when he saw the character in the movie )

one of my friends don't put his photo as a profile picture, he keeps putting colors. once White, once Blue, once Orange .... etc. on Facebook

and when I ask him why ? he says, it's personal..

why do u think he's doing that ?

he's 29 yrs old.

find the equations of the tangent and the perpendicular (on tangent) which make an isosceles triangle with the x-axis

( i.e: the triangle consists of the tangent and the perpendicular and the x-axis)

How could

X + 2 = X

??????

some say X= infinity or - infinity

is this correct ?

while I'm studying mathematics , I go through big functions like : f(x) = sec(x)^4/( tan(x)^2 + 2tan(x)+1) or g(x) = e^3x / (e^2x + sqrt(x-3)e^x ) then the question goes like : find the integration or the area under the curve... now, my question is : why???? what is the use of integrating such functions ? where shall I use them later , in physics, in engineering in .... ?

seriously, i'm not complaining, i'm just trying to expand my knowledge :)

while I'm studying mathematics , I go through weird functions like :

f(x) = sec(x)^4/( tan(x)^2 + 2tan(x)+1)

or

g(x) = e^3x / (e^2x + sqrt(x-3)e^x )

then the question goes like : find the integration or the area under the curve...

now, my question is : WHY ? why would someone ever need this ? who needs such functions and where do they use them?

I have thousands of videos on my PC , with all kinds of extensions ( .AVI . FLV . 3gp . .... etc ) ...

Before formatting my PC, I used to play them all without any kind of problems, but now, After formatting my PC , some of them ( not all ) are stuck and couldn't be played ( when I single click on the video, the computer takes a long time to preview it, then, I double click on it, it opens but very very very slow ) ...

Note: I use Windows Media Player latest version, and Media Player Classic latest version, and FLV player latest version... and all of them have the same problem.

Note : I use K-Lite Codecs , latest version . ( I also used them before formatting )
