You just saved my life ,I have exams tomorrow and I'm just understanding this now 😊

Nice

Thank you

[@hipmugger5952]

Does it have different methods,i see other tutorials using something cos+isin?

[@SkanCityAcademy_SirJohn]

yes please there are other methods, kindly see video 7a of the same playlist (Linear Algebra) for that method

@@SkanCityAcademy_SirJohn thanks a bunch you so hepful.

[@edmondafoakwa3232]

Please sir what if upon adding the angle it becomes greater than 360

[@SkanCityAcademy_SirJohn]

It's unlikely for the angle to be greater than 360. You know the complex number is symmetrically spaced by 360/n, so the last root will have and angel within 360 or 360.
Hope the explanation is okay
