Not quite sure what you are asking for with "formula"
Standard Form: a + bi
Polar Form: rcos(t) + irsint(t)
Exponential Form: re^it
I'm sorry, I'm speak English not quiet good so it's very hard to translate. It's the formulas to calculate complex number
Do you mean arg()?
That formula list in the docx file is quite a mouth full. In the long run you might be better off just to learn how to use DeMoivre's Theorem and Exponential Form and apply them to each individual case.
My 2 cents anyway.
