1)make Compare between z,w

2)find z!

3)IzI=sqart root (z^2)

or IzI=sqart root(zz')

IzI=sqart root (z^2)=sqart root(zz')

4) Compare between 1,i

5) i!=????

2. Is "!" supposed to be the factorial? It's only defined for positive integers, not complex numbers.

3. If, by ', you mean "complex conjugate", then [itex]|z|= \sqrt{zz'}[/itex] which is NOT the same as [itex]\sqrt{z^2}[/itex] unless z is real.

5. Suppose f(z) = 3xy + i(x-y^2). Find lim{z -> 3+2i} of f(z), or explain carefully why it does not exist.

I am unaware of any definition of "less than" or "greater than" concerning complex numbers.I mean

Z<W OR W<Z

1. What do you mean by "compare"? Find the difference? Absolute value of difference?

Neither. The field of complex numbers is NOT an "ordered field".I mean

Z<W OR W<Z
