Please help me to solve the differential equation in attached file.

What attached file? Unless it's me, I see no file.

Nope, there really aren't any attached files galactus...

Yes, and how much do you want to bet they never respond back?

LOL! 10 greenies! :cool:

:)Hi, I do not know why the attached file was indivisible, mast be It was my inattention. Anyway I have already solved the equation. :cool: Do not wary, soon I will be back with another one, more complicated.
Or, may be, with the system of PDE.

Anyway Great Tanks for Replies!:)

LOL! You won galactus!

Ok, Karik, that doesn't matter. Try going to

And look for the sticky thread. You'll have a program for LaTeX, enabling you to post functions amongst others.

You send me on a nothing :(
The link is go to a Forum that no longer is available.

Here is a link to the LaTeX tutorial.

Here's a link to the message describing LaTeX:

and finally, here's a link that Unknown008 meant to post

Basically, you start the equation with "[math]" , then enter the LaTeX stuff. Finally, you finish it with "[/ math]" (except don't enter the space between the "/" and "math". I had to do that to prevent the system from recognizing it as a LaTeX statement).

Oh! I saw my mistake... :o The link was 'math' and not 'maths'. Sorry, but hopefully, Perito was there. :) Thanks! :)
