The motion of a point P in the complex plane is defined by the principal root of z^5= (1+ t)^i a)find z(t) b)Show that P is undergoing a circular motion. Find the velocity and acceleration as a function of time I'm pretty sure I know how to do b but I don't really understand the wording of the question. A is really confusing me. The 'Principal root' would that mean I have to take the root of both sides? and then just rearrange and isolate z?
