WebSep 22, 2024 · We can see from the graph of 1 / x that as x approaches infinity, f ( x) = 1 / x approaches 0. Therefore, solving 1 / ∞ is the same as solving for the limit of 1 / x as x approaches infinity. Thus, using the definition of limit, 1 divided by infinity is equal to 0. Henceforth, we will consider infinity not as a real number where usual ...
