About the Limit Calculator
A limit calculator with left/right limits and L'Hôpital's rule, in your browser.
What it is
The Limit Calculator evaluates the limit of a function as x approaches a finite value or infinity. It computes left-hand and right-hand limits numerically, checks whether they agree, and applies L'Hôpital's rule automatically when it detects a 0/0 or ∞/∞ indeterminate form in a quotient.
Features
Finite and infinite limits
Approach any finite value, or evaluate behavior as x → ∞ or x → −∞.
One-sided limits
See the left-hand and right-hand limits separately, and whether they agree.
L'Hôpital's rule
Automatic detection of 0/0 and ∞/∞ forms with the derivative-based resolution shown.
