 Summand
 find the summands in an expression Calling Sequence Summand(f) Parameters

 f - algebraic expression or list, set, or rtable of algebraic expressions Description

 • The Summand(f) command returns a list containing the summands found in f, sorted by summation nesting level. Examples

 ${R}{≔}\frac{{3}{}\left({\sum }_{{i}{=}{0}}^{{9}}{}\left({\mathrm{sin}}{}\left(\frac{{3}{}{i}}{{10}}{+}\frac{{3}}{{20}}\right){+}{3}\right)\right)}{{10}}$ (1)

 $\left[{\mathrm{sin}}{}\left(\frac{{3}{}{i}}{{10}}{+}\frac{{3}}{{20}}\right){+}{3}\right]$ (2)
 > $\mathrm{Summand}\left(\mathrm{Sum}\left(\frac{1}{{n}^{2}},n=1..\mathrm{\infty }\right)\right)$
 $\left[\frac{{1}}{{{n}}^{{2}}}\right]$ (3)
