Summary Let ϕ ν (x) (ν=1, ...,n) ben elementary functions, such that the integrals ϕ ν (x)=∫ϕ ν dx are not elementary. Then, if there exists a relationF(ψ 1, ...,ψ n,x)=0 with an elementary functionF(W 1, ...,W n,x) of itsn+1 variables, there exists also alinear relation $$\mathop \sum \limits_{v = 1}^n \alpha _v \psi _v (x) = \psi (x)$$ where α ν are constants andψ(x) is an elementary function.
