How do you evaluate a limit?

Start with direct substitution. If that gives an indeterminate form like 0/0, apply techniques like factoring, rationalization, or L'Hopital's rule. This calculator shows which method applies and walks through each step.

What is L'Hopital's rule?

L'Hopital's rule says that if a limit gives 0/0 or infinity/infinity, you can take the derivative of the numerator and denominator separately and re-evaluate the limit.

Can this calculator handle limits at infinity?

Yes. Enter limits at infinity using 'oo' for infinity, e.g. limit(1/x, x, oo). The solver shows how the function behaves as x grows without bound.
