I would like to know what the French verb is for 'to differentiate' and 'to integrate', as in

“I am differentiating the curve y = x^2”


“I am integrating the line y = 3x”.

I checked Collins English-French Dictionary and it wasn't so helpful.

The verb "dériver" has two important meanings in mathematics:

  1. to obtain the derivative of a function; it's the translation of "to differentiate" in the present case.

    ex: Si on dérive f(x)=x² on obtient f'(x)=2x.

  2. to deduce a mathemetical fact through the use of logical principles and principles of the theory at hand; in other words to prove a theorem or a lemma; it's then the translation of "to deduce" or "to derive".

ex: On dérive ce théorème à partir des théorèmes 3, 4, et 5 de la section précédente.

  1. For the verb "to integrate" there is no other word in French than "intégrer".

ex: Si on intègre la fonction exponentielle on obtient encore la fonction exponentielle.


You will translate as in the following:

to differentiate = dériver

to integrate = intégrer

edit: if I look for the meaning of differentiate, the definition match with french dériver (If I dérive f(x) = x^2 I got f'(x)=2x). but if I look for the translation of dériver in maths meaning I got to derive.

Are to differentiate and to derivesynonyms?
