Use
the numbered buttons to select an integer n betweeen 2 and 9.
Select
a complex number z, marked by a cyan diamond and radius vector, by dragging
the cursor or by grabbing the [angle] or [modulus] slider. The n nth
roots are displayed in yellow, with green radial vectors. The unit circle
is displayed in gray, and the circle through the nth roots
is displayed in blue.
Use
the [zoom] key to adjust the size of the graphing window.
To
the right, the number z is read out. Below that, use the buttons to
display a representation of the modulus of z and of its roots, or of
the angle of z and of its prinicipal root, or of the values of the n
nth roots, or none of these.
