# Limits

Limits are the underlying tool used in calculus, appearing in the definitions of continuity, derivatives and integrals. Wolfram|Alpha has the power to compute bidirectional limits, one-sided limits, supremum and infimum limits, discrete limits and multivariable limits. More information, such as plots and series expansions, is provided to enhance mathematical intuition about a limit.

Compute limits numerically and symbolically.

#### Compute a multidimensional limit:

#### Find the value of a nested limit:

Evaluate limiting behavior of sequences.

#### Compute discrete limits:

#### Compute discrete supremum or infimum limits:

Compute one-sided limits from a specified direction.

#### Compute one-sided limits at a point of discontinuity:
