Zero divisors: continuous functions over R

  1. Nov 25, 2007 #1
    Does the ring of continuous functions over the real numbers have no zero divisors? If no 0 divisor, how can I prove it? Else, what is a counter example?

    you should be able to define two nonzero continuous functions whose product is zero function...

    Keep in mind if a function is defined piecewise such that each piece is continuous, and all the endpoints match up, you've defined a new continuous function
