Solve the following differential equation:
x''+(c/x^2)=0 . Solve for x in terms of t.

to reduce this to
x' = sqrt( v0^2 - 2 c (1/x0 - 1/x ) ) which is another 'simple'
differential equation.
Just write it as
dx / sqrt( v0^2 - 2 c (1/x0 - 1/x ) ) = dt
and integrate between t0 and t to find t(x).
Then 'simply' invert to find x(t) ;-)

HAHAHAHA! What a classic!
I gotta keep that one!

Yes, keep it with the pictures of your daugther.

Dirk, have you no decency at all?. ... Sheesh!

When you step in a dog turd, you scrape the **** from .

Sheesh, Dirk! First you tell the world that you hate and
ridicule a grieving dad for the tragic loss of his daughter
and now you say that you hate animals too... My gawd,
Dirk, are you drunk or loaded this Saturday eve and/or
are you having mental problems because it is full moon
tonight?. --- No wonder they fired you, with you exhibiting
such a calloused, sociopathic outlook on life.
BTW, you are a daddy too, aren't you?

I expect he put his balls on the line once to often and they were bitten
off by a larger dog that was not quite the local village idiot.
Did you notice he writes castrato? In most pee puppies the vocal cords
and writing chords do not change after puberty. He earned the name
"pee puppy" from Sue Jahn because he ****es on everyone's leg.

A few years ago the Dork found it funny when I said the solution to a
differential equation was a function, but even Wackypedia has since
born me out.
http://en.wikipedia.org/wiki/Differential_equation
"A solution to a differential equation is a function"
Why bark yourself when you own a dog?

Dork cannot accept that I am a mathematician because I oppose
Einstein. He didn't realize that the 'c' in x'' + (c/x^2) = 0 was not
Einstein's velocity of light but a general constant, or that x''
was the second derivative of x with respect to t, d^2x/dx^2.
What a Dork!
I won't go into detail on what Dork wrote above,
"Just write it as dx / sqrt( v0^2 - 2 c (1/x0 - 1/x ) ) = dt",
but dx * a = dt?
That's like meters = seconds, totally ****in' psychotic.

To me it is clear that the guy asking the question is no fool, so who
the **** does Dork think he's impressing?
His lover, YBM (Your Basic Moron)?
They went on vacation together, I'm fairly sure they are faggots.
It's a beautiful choir.


On another note (more bass than soprano or castrato), I still miss my
daughter but I'm able to sleep now. The Dork cannot cause me pain,
but I appreciate your concern and humanity.
Thank you.
Keep on laughing, it is appreciated more than you realize.
