I didn't solve the equation yet. :frown:
The second equation is nonlinear... From the nonlinear equation through some perturbations I concluded to the first linear non-homogeneous equation...
But still no solution... I am trying different methods but no solution...
I know that is solvable...
Hello forum,
I am trying to solve a differential equation for the last four hours and I can't figure out how...
here it is
\frac{d^2x(t)}{dt^2} + \frac{dx(t)}{dt} + c x(t) = d e^{-a t^2}
actually my problem is how to handle the Gaussian term...
if anyone can help please...
Thank you very much xepma !
Your solution solves my problem. I didn't know about these techniques with contour integrals.
But I would also like to make a comment about the answer,
The correct answer is only R^2 B_z (\pi - \epsilon ) when \epsilon \to 0 , and is not valid when \epsilon = 0...
I was reading an article about the Aharonov - Bohm effect and gauge invariance ( J. Phys. A: Math. Gen. 16 (1983) 2173-2177 ) and there is something I really don't get it.
The facts are:
The problem is the familiar Aharonov-Bohm one, in which we have a cylinder and inside the cylinder \rho...
The question is about LaTeX...
It will take hours to replace one by one the symbol \imath, because the document is more than 150 pages and more than 400 equations.
change imath command (LaTeX)
Hello,
I have a question about the \imath command... :confused:
I am a physics student and I wrote a huge document with many equations. In some equations there is the \imath symbol. When my professor saw this document he told me to change the symbol and use one...
