Homework Help: Zero's and roots

  1. Feb 19, 2008 #1
    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.

    i think when reffering to polynomials zeros and roots refere to the same thing, however when refering 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!

    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.
