I have been trying to determine a good way to filter complex
expressions from a Sequence. Here is an example:
sage: a = 879 == 265 * e^(20 * r)
sage: solve(a,r)
[r == log(879^(1/20)*e^(I*pi/10)/265^(1/20)), r ==
log(879^(1/20)*e^(I*pi/5)/265^(1/20)), r ==
log(879^(1/20)*e^(3*I*pi/10)/265^(1/20

Yep. If you want I to be a symbolic variable do
sage: I = var('I')
sage: a = E == I * R
sage: solve(a, R)
[R == (E/I)]
In general, it is always a good idea to use the var command to
explicitly construct
Because I is the square root of -1.
sage: type(I)
sage: type(J)
sage: type(R)
Yeah this is pretty confusing if it's not what you expected.

Does anyone have any thoughts on why solve() returns [R == -1*I*E] in
the following SAGE session?
Thanks in advance :-)
