You might get a question where you end up with something like 17 pi and would be expected to know that if this is an argument then pi is also an argument, but getting the exact value with numerical coefficients wouldn’t be expected. I hope that makes sense.

All the best,

this is a bit of a delayed reaction, above when we want to calculate the 17th power of the complex number and we reach the point where the angle is 15.764…. in a test situation will we be expected to know the value of 2.pi of will simply leaving in as (15.764…- (n)(2.pi)) be enough. let me know if my question is not so clear and ill try and rephrase.
