#### Search: #### Defint

Function: defint (<expr>, <x>, <a>, <b>) Attempts to compute a definite integral. `defint` is called by `integrate` when limits of integration are specified, i.e., when `integrate` is called as `integrate (<expr>, <x>, <a>, <b>)`. Thus from the users point of view, it is sufficient to call `integrate`. `defint` returns a symbolic expression, either the computed integral or the noun form of the integral. See `quad_qag` and related functions for numerical approximation of definite integrals.

There are also some inexact matches for `defint`. Try `?? defint` to see them.

(%i2) ```
