The question is :
The complex number [tex]z[/tex] is given by
z = 1 + cos (theta) + i*sin (theta)
where -Pi < theta <= Pi
Show that for all values of theta, the point representing z in a Argrand Diagram is located on a circle. Find the centre and radius of the circle.
Note that i understand perhaps some of you don't understand the symbol i used above, hence i will explain it here :
smaller or equal to : <=
theta : an angle
Pi : a usefull constant in circle, i don't know how to define it.
i = square root of -1
