    I'm doing revision for next semesters exams and I ran across this:

    http://mathworld.wolfram.com/EulerFormula.html

    Specifically formula no.8. I've seen it before but can't find it in my notes, I forgot what splitting

    [tex]{\frac {d z}{d\theta}} [/tex]

    on either side of the equals sign was called. But I do remember being warned not to think that it is just division.
