## What is a limit in calculus? |

A limit is a fundamental concept in calculus. Unlike a limit mentioned above (as in a series or sequence), a limit of a function in calculus takes on a somewhat different meaning. In particular, a limit of a function can be described as the following: If *f(x)* is a function defined around a point *c* (but may not be at *c* itself), the formal limit equation becomes:

Thus, the number *L* is called the limit of *f(x)* when *x* goes to *c*.
