Student[MultivariateCalculus]

 diff

 Calling Sequence diff(v, n)

Parameters

 a - Vector or with algebraic entries or an algebraic expression n - name, sequence of names, or list of names

Description

 • The diff command extends the top level command diff in such a way that when v is a Vector, each component of v is differentiated. If v is anything else, then the top level diff is applied directly.

Examples

 > $\mathrm{with}\left(\mathrm{Student}:-\mathrm{MultivariateCalculus}\right):$
 > $v≔⟨{x}^{2},xy⟩$
 ${v}{≔}\left[\begin{array}{c}{{x}}^{{2}}\\ {x}{}{y}\end{array}\right]$ (1)
 > $\frac{\partial }{\partial x}v$
 $\left[\begin{array}{c}{2}{}{x}\\ {y}\end{array}\right]$ (2)
 > $\frac{{\partial }^{2}}{\partial y\partial x}v$
 $\left[\begin{array}{c}{0}\\ {1}\end{array}\right]$ (3)

Compatibility

 • The Student[MultivariateCalculus][diff] command was introduced in Maple 2016.
