ABSTRACT: It is well known that the notion of integral in mathematic branch is among the most difficult contrarily to some known techniques as integration by part or by change of variable, the integral is forgotten. The mathematic theories contain other notions having the applications which allow to determine the integral of some types of functions, for instance Laurent’s series, Beta’s functions, Gamma’s functions, Laplace’s transformations,…There is a way to wonder if those notions can be taught at the secondary school for resolving major problems of some types of non –integrals functions by part or variable change. This should allow us to legitimate the teacher who is always absorbed by difficult questions that learners of mathematics come across. Thus, our goal is to propose remedial techniques to calculate the integral based on Laplace’s transformation which the basic knowledge is not contrary to Laplace’s transformation defined thanks to an integral what means that the present notions can be accommodated to the rest of integral proposed in the 6 th form of scientific section in our country
