What this result means

Free limit calculator to calculate function limit. Instant results in your browser — no signup. Continuous functions: substitute. 0/0 rational: cancel (x−a) when possible.

Assumptions

Rule dependency: Universal formula.

How is it calculated?

Continuous functions: substitute. 0/0 rational: cancel (x−a) when possible.

Example

(x²−4)/(x−2) at x=2 → cancel to x+2 → limit 4.
