  1. Try this on your calculator
    5/.01 = ..
    5/.00001 =
    5/.0000001 =

    notice I am making my divisor smaller and smaller, almost zero and what is happening to your answer?

    The closer my divisor gets to zero, the larger the answer.
    So when I could actually divide by zero, then the answer should be infinitely large
    which of course is not a number, thus we call it "undefined"

  2. Or, consider this. Suppose 4/0 = x for some value of x.

    To clear the fraction, we get 4 = 0*x

    But 0 times any number is zero. So, there is no possible value of x for which 0*x = 4. (Or any other nonzero value)

    Am I correct to say that 5/0 = 5 or is it undefined no your ar incorrect becuase you cant divide 5 by 5 to get 5 dividing by is is impossible and it is undefined Zero (0) will go into 5 — any other integer — an infinite number

    For what values of x is an element of real numbers, will y = 1/sin(x) be undefined? (Where x is understood to be measured in degrees.) I know that for it to be undefined, sin(x) must be 0. Given this I know that x is undefined at:
