In reading a math paper, I came across the following sentence:
Si l'on remplace les dérivées et/ou primitives littérales par leurs approximations, l'équation cesse d'être exactement vérifiée.
The way I understand it, this means
If we replace the literal derivatives and/or antiderivatives with their approximations, the equation will no longer be exactly "verified".
I am uncertain as to what "vérifiée" means in this context. The following source (regarding vérifier) does not seem to quite cover the connotation: http://stella.atilf.fr/Dendien/scripts/tlfiv5/search.exe?25;s=2724010470;cat=0;m=v%82rifier;
MATH. Vérifier une équation. Faire de cette équation une équation juste.
From context, it means that the equation will become an approximation of itself, and no longer a proper equation, but I do not know how to translate that properly.
