Padé approximants often provide more accurate approximations to a function near singularities than truncated Taylor series do.

The static analyzer is over-approximating the set of possible variable values, which causes many false positives during verification.

Many researchers compare approximation algorithms to evaluate trade-offs between accuracy and running time.

When evaluating integrals with rapidly oscillating integrands, physicists often invoke the stationary phase approximation to estimate the leading contributions.

He estimated the journey would take approximatedly three hours.
