Through the paper on Laplace transformation integration published in CERIGO Journal N°2 pp. 75-86, senior lecturer David BYAMUNGU has shown basis actuality and the importance of Laplace transformation integration of some functions that do not accept usual methods integration such as integration of part and variable change; these notions being considered as one of most important mathematic theories.
In the same way, the present paper brings about and exhibits the importance of scientific interdisciplinarity showing that from transformational calculation of Laplace we can resolve problems linked with solution to problem of interdisciplinarity happening to show how transformational calculation of Laplace plays a very basic role in Mathematics (Analysis), Physics, electronics and other branches of science.
By this study we want to know the degree knowledge of Goma students about relatives numbers. Can the vacation of the school have an incidence to the performance of students or to be girl or boy can come above it.
