Query: About equality of the cosine transform to the sine transform of Fourier
  and the transform of Laplace   Regularity of the transform of Laplace in the opened area of 0 is proved with
help of some methods of the transform of Fourier. The class of the transform of
Laplace from the transform of Fourier is considered from some functions without
a regularity in null.
  The functions are regular in the opened area of 0.
