z=e^(2 times pi times i times t)
If t goes from 0 to 1, then you get the unit circle.

The complex number of the equation z = x + iy is x.
the number that is part of the x-term
The complex roots of an equation are the complex numbers that are solutions to the equation.
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
Because of how close the two are. The only difference between the two is that a complex number is any whole number along side of a fraction, while a real number is any positive number.
