[Maxima-discuss] collecting constant terms using substinpart

[nijso b. <ni...@ho...>]

Hi,

I want a*exp(x+2)/b to be split into [a,1/b,exp(x),exp(2)] so I can
collect the constant terms.

(%i2) substinpart("[",a/b,0);
(%o2) [a,1/b]
(%i4) substinpart("[",exp(x+2),0);
(%o4) [%e,x+2]

but the internal representations of a/b and exp(x+2) are:

((MTIMES SIMP) $A ((MEXPT SIMP) $B -1))
((MTIMES SIMP) ((MEXPT) $%E 2) ((MEXPT) $%E $X))

I guess I still don't understand exactly how substinpart works. Why is
substinpart not working on exp(x+2)? In both cases, "*" is the first
operator mentioned in the internal representation, but also inpart(exp(x
+2),0) says the first operator is "^".


Best,
Nijso
