324:(namely division of the polynomial by a factor corresponding to the root), and that only if the root still persists as a solution of te new problem does one consider it to occur more than once. The text already says this, and the lead section already says that multiplicity in general means being present multiple times, when a precise meaning can be given to that. So what does the sentence really add?

isn't, I think none of the definitions given applies, so one can only conclude that the zero has no multiplicity at all (not even multiplicity zero). Other problematic points are infinite multiplicities (which are not allowed in the most common definition of multiset; even those who prefer to be more liberal make it a

The problem is that this is just informal language; there is no such thing as "occurring as a solution" in general; a value either is a solution of a problem, or it isn't. The reason that one can define multiplicity in the case of a polynomial equation is that there is a method to "remove" a solution

Hey guys, I appreciate the precise mathematical definition of the multiplicity of the zeros of a function, but how about a simple one line explanation that the multiplicity of a root is the number of times that root is repeated? Followed by a simple example, like the root of f(x) = (x-1)^3 is 1, with

This could be something simple, like "if k is an underestimate, then the limit evaluates to 0, and if k is an overestimate, then the limit evaluates to ∞, which is not a real number." Or it could give a full-fledged derivation for why both of these is the case. Regardless, an explanation is needed,

In its current state, this section is not correctly formulated, and is a very bad illustration of the general notion of multiplicity. Since nothing is required of the function (an indeed the interval is not even required to not be reduced to a point), it need not be continuous at its zero; if it

Can anyone suggest a better way of resolving this confusion? I do not now have time to look into this further, but perhaps we have somewhere else an article which includes a description of his ideas of "multiplicity", and we could link
