convert/diff

convert an expression of the form D(f)(x) to diff(f(x),x)

 Calling Sequence convert( expr, diff);

Parameters

Description

 • The command, convert(expr,diff) replaces, where possible, the use of the D operator by the use of the diff function in the expression expr.

Examples

 > $g≔{\mathrm{D}}^{\left(2\right)}\left(y\right)\left(x\right)-a\mathrm{D}\left(z\right)\left(x\right)+\mathrm{D}[2]\left(f\right)\left(x,y\right):$
 > $\mathrm{convert}\left(g,\mathrm{diff}\right)$
 $\frac{{{ⅆ}}^{{2}}}{{ⅆ}{{x}}^{{2}}}{}{y}{}\left({x}\right){-}{a}{}\left(\frac{{ⅆ}}{{ⅆ}{x}}{}{z}{}\left({x}\right)\right){+}\frac{{\partial }}{{\partial }{y}}{}{f}{}\left({x}{,}{y}\right)$ (1)
