Are we always having problems with your PC? Are you constantly seeking methods to grow PC performance? Then this really is the post you're lookin for.

You'll see this issue right away, incredibly should you have lower than a gig of RAM. Most modern computers come with a least that much.

	~~==Multiplicity~~ of a ~~zero==~~
	~~A complex number ''a'' is a '''simple zero''' of ''f''~~, ~~or a '''zero~~ of ~~multiplicity 1'''~~ of ~~''f''~~, ~~if ''f'' can~~ be ~~written as~~

	:<~~math~~>~~f(z)=(z-a)g(z)\,~~<~~/math~~>

	~~where ''g'' is a [[holomorphic function]] ''g'' such that ''g''(''a'') is not zero.~~

	~~Generally,~~ the ~~'''[[multiplicity (mathematics)\|multiplicity]]''' of~~ the ~~zero of ''f'' at ''~~a'' is the ~~positive integer ''n'' for which there is~~ a ~~holomorphic function ''g'' such that~~

	:<~~math~~>~~f(z)=(z-a)^ng(z)\ \mbox{and}\ g(a)\neq 0.\,~~<~~/math~~>

	~~The multiplicity~~ of a ~~zero ''~~a~~'' is also known as the '''order of vanishing'''~~ of the ~~function~~ at ~~''a''~~.

	~~==Existence of zeros==~~
	~~The [[fundamental theorem~~ of ~~algebra]] says that every nonconstant [[polynomial]] with complex coefficients has at least one zero in~~ the [~~[complex plane]~~]. This ~~is in contrast~~ to the ~~situation with [[real number\|real]] zeros: some polynomial functions with real coefficients have no real zeros~~. ~~An example is ''f''(''x'') = ''x''~~<~~sup~~>2<~~/sup~~> ~~+ 1~~.

	~~==Properties==~~
	~~An important property of the set of zeros~~ of a ~~holomorphic function of one variable (that is not identically zero) is~~ that ~~the zeros are isolated~~. ~~In other words~~, ~~for any zero of~~ a ~~holomorphic function there is a small disc around the zero which contains no other zeros~~.
	~~There are also some theorems in complex analysis which show~~ the ~~connections between the zeros~~ of a ~~holomorphic (~~or ~~meromorphic) function and other properties of the function~~. ~~In particular [[Jensen's formula]] and [[Weierstrass factorization theorem]] are results for complex functions which~~ have ~~no counterpart for functions of~~ a ~~real variable.~~

			==Multiplicity of a zero==
			A complex number ''a'' is a '''simple zero''' of ''f'', or a '''zero of multiplicity 1''' of ''f'', if ''f'' can be written as

			where ''g'' is a [[holomorphic function]] ''g'' such that ''g''(''a'') is not zero.

			The multiplicity of a zero ''a'' is also known as the '''order of vanishing''' of the function at ''a''.

			==Existence of zeros==
			The [[fundamental theorem of algebra]] says that every nonconstant [[polynomial]] with complex coefficients has at least one zero in the [[complex plane]]. This is in contrast to the situation with [[real number\|real]] zeros: some polynomial functions with real coefficients have no real zeros. An example is ''f''(''x'') = ''x''<sup>2</sup> + 1.

			==Properties==
			An important property of the set of zeros of a holomorphic function of one variable (that is not identically zero) is that the zeros are isolated. In other words, for any zero of a holomorphic function there is a small disc around the zero which contains no other zeros.
			There are also some theorems in complex analysis which show the connections between the zeros of a holomorphic (or meromorphic) function and other properties of the function. In particular [[Jensen's formula]] and [[Weierstrass factorization theorem]] are results for complex functions which have no counterpart for functions of a real variable.
