Philip A. Nelson isn't an author of bc, he's an author of GNU bc. If he's to be credited there (which he shouldn't be) then Gavin Howard and Otto Moerbeek should also be credited there. Philip is credited for his actual contributions later in the article, so there's no loss of information. |
Correct reference. Only Unix man pages, or Unix standards documents, should be used as references for Unix programs. The same GNU bc man page is still listed further down, so no information is lost. |

Line 98:
bc's standard math library (defined with the '''-l''' option) contains functions for calculating [[sine]], [[cosine]], [[arctangent]], [[natural logarithm]], the [[exponential function]] and the two parameter [[Bessel function]] ''J''. Most standard mathematical functions (including the other inverse trigonometric functions) can be constructed using these. See external links for implementations of many other functions.
