I am an engineer who is in love with math and lifelong math student. I love to learn new things in mathematics for self-satisfaction. My idols are Gauss , Euler , Ramanujan because they were in love with math as I feel.

comment To simplify $f_a(x)= \int_{-a}^{+a} e^ {-\frac{x}{t^2-a^2}}\;dt$
Could you please give more detail how you got that result? Thanks

Yes you are right typo should be x<=0 . Thanks a lot.

comment How to define the transform?
@RobertMastragostino: if I could not explain it clearly, let me explain my problem in different way. İmagine there is a fixed wall at $x_1$ and height of it is $f(x_1)$. You have a wire that curved as $f(x)$ and also the shape of wire does not change.The wire is not fixed to wall, it is just on wall. It is fixed on point A. You hold the wire from Point A and you fix it in different point A' on x axis and then you let rotate the wire till placing on the wall (point B). Thanks a lot for your contribution and advice.
