'''Multivariable calculus''' (also known as '''multivariate calculus''') is the extension of [[calculus]] in one [[Variable (mathematics)|variable]] to calculus with [[Function of several real variables|functions of several variables]]: the [[Differential calculus|differentiation]] and [[integral|integration]] of functions involving multiple variables (''[[multivariate (mathematics)|multivariate]]''), rather than just one.<ref name="CourantJohn1999">{{cite book|author1=Richard Courant|author2=Fritz John|title=Introduction to Calculus and Analysis Volume II/2|date=14 December 1999|publisher=Springer Science & Business Media|isbn=978-3-540-66570-0}}</ref> 

Multivariable calculus may be thought of as an elementary part of [[calculus on Euclidean space]]. The special case of calculus in three dimensional space is often called ''[[vector calculus]]''.
