Multivariable Calculus refers to Calculus involving functions of more than one variable,
i.e., multivariable functions. Not surprisingly, it is important that the reader have a
good command of one-variable Calculus, both di?erential and integral Calculus, before
diving into multivariable Calculus.
Several aspects of multivariable Calculus are quite simple. Partial derivatives are just
one-variable derivatives, in which you treat all other independent variables as constants.
Iterated integrals are the analogous concept for integration; the integrals involved are
?partial integrals? (though no one calls them that).
