Complex function fails

I try to visualize complex polynoms http://weitz.de/fund/


and do the calculation by transfer of polynom variables to polar coordinates. I have 2 function to calculate the modulus preal(o, j ) and the angle pimag(o, j , t)


1. Bug


after definition of pimag(o, j , t) the argument list was changed to pimag( j, o , t)

- it cost some time to recognize that


2. Bug


if argument o is a complex number or variable (a_1...a_5) the functions preal/pimag fail in AlgebraView, but works in CAS

- see Points A, Z_3


in second App of

Any idea?
