Hi,
Am trying to expand formulas with complex values.
E.g.:
(%i1) declare(b,complex);
(%o1) done
(%i2) (a+b)^2;
2
(%o2) (b + a)
(%i3) expand(%i2);
2 2
(%o3) b + 2 a b + a
(%i4) realpart(expand(%i2));
2 2 2
(%o4) realpart (b) + 2 a realpart(b) - imagpart (b) + a
(%i5)
But this seems to be wrong.
As far as I know (a+b.i)^2 would be something like:
re: a^2-y^2
im: 2.a.b.i
What am I doing wrong?
