a type of variable that can have an infinite number of values within a specified range is
Continuous or discrete variable A continuous variable is one which can take on infinitely many, uncountable values.
Limit of a function (the Dirichlet function) has no limit at any x-coordinate.
1 + 2 + 3 + 4 + ⋯ which increases without bound as n goes to infinity. Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sum.
Exponentiation Any nonzero number raised to the 0 power is 1:[11]
