Sorry this is so general but I really need some help with evaluating complex numbers.
I am trying to do the following:
I am starting with an expression of the form...
[complex number (complex number - real number)]/[(complex number- real number) (complex number - real number) - complex number
1) I would like to solve this expression so that it is in a + ib format.
2) Then, I would like to convert this form into polar coordinates...r(cos[phi] + i sin[phi]) where r = Sqrt[a square + b square] and phi = arctan[b/a].
3) Then I would like to take the real part of the expression...so it would be only r Cos[phi].
I know the command for the last step is Re[]. Does anyone know the commands for the other two steps?
Thank you.
