Homework Help Overview

The discussion revolves around the concepts of zeros and roots in mathematics, particularly in the context of polynomials and functions. The original poster questions whether zeros and roots are equivalent terms, citing a specific problem that asks about both concepts.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Some participants explore the definitions of zeros and roots, questioning whether they can be used interchangeably in different contexts. Others express uncertainty about the terminology used in mathematics, particularly in relation to functions and equations.

Discussion Status

The discussion is ongoing, with differing opinions on whether zeros and roots are the same. Some participants assert that they are equivalent in the context of polynomials, while others argue for a more nuanced distinction based on the definitions of functions and equations. There is no explicit consensus, but various interpretations are being explored.

Contextual Notes

Participants note that terminology can vary and that there may be a lack of clarity in how these terms are used in different mathematical contexts. The discussion reflects an exploration of these definitions rather than a resolution.

zero's and roots...

Zero's are the same thing as roots, correct?

I have a question where a) askes what's the zero's. Then b) asks what are the roots.


pretty sure it's the same.
 
Physics news on Phys.org
i think when referring to polynomials zeros and roots refere to the same thing, however when referring to functions i think that we cannot reffer to it as the roots of a function, but only we should referr as the zeros of a function.
I am not quite sure though!

you're right they are the same:

No, they are not the same. Not if you are being very "correct".

A root of an equation is any solution to that equation.

A zero of a function, f(x), is any solution to the equation, f(x)= 0.

I see that Wikipedia says the opposite, saying that a "root of a function" is the same as a "zero of a function" but I think that is very sloppy terminology. Unfortunately even mathematicians get sloppy sometimes.
