What are non-vanishing and vanishing numbers? |
A non-vanishing number is just as the term implies: A quantity that is non-zero everywhere. For example, in the expression x4 + 1, the answer will never be zero (even when x is zero or a negative number). The answer for the expression x2 is called “vanishing” because if x = 0, the expression’s answer “vanishes” to zero.
