Hallo
I have sequence of terms (sums) such as:
lst: a*EXP(-b*r)*F(c*r)/r^n
where n varies from 1..7, F can be SIN or COS. I wish to extract
coefficients of r, r^2 .... r^7 and
subsequently, delete these terms from the original lst.
Example:
CO1 : COEFF(lst, r,-1)$
Now how to eliminate the terms CO1 from the lst?
DELETE(CO1, lst) does not work as the function DELETE should be applied to
every term of the list individually.
Any help is appreciated
