- And calculate
which is an elementary Monte Carlo integral with

**x**and**y**generated independently between**-1**and 1. - Actually, the brute force method (generate
**x**uniformly between**-1**and 1,**y**uniformly between ) is more efficient---in the language of (NI.16) this second method has a smaller variance. - However, use of bounding boxes is an important technique for it
is often impossible to find ranges analytically while it is easy to
decide if a given lies within range of integration.
