If I am calculating roots in polar form how should I be displaying them?
eg. The seventh roots of -128 are:
Do I need to be displaying them like this?
Or like in the first example
The reason I ask is because i'm asked to show how they make 3 complex conjugate pairs which I can see are
Thanks for the explanation about the arg!!
Another reason I ask is that the follow on question asks me to factorise the polynomial
I've worked out that one of the roots are and another is hence my question about the polar forms as I feel i'm duplicating my work
Any advice would be great
