This is documentation for Mathematica 6, which was
based on an earlier version of the Wolfram Language.
 Elementary Functions Using the latest platform-optimized code, Mathematica not only delivers high-efficiency machine-precision evaluation of elementary functions, but also—using a number of original algorithms—provides the world's fastest arbitrary-precision evaluation. A sophisticated web of symbolic functions and transformations allows Mathematica to perform exact numerical and algebraic operations on elementary functions—effortlessly obtaining results that in the past would have been viewed as major mathematical accomplishments. Log — base-e logarithm (Log[b, x] uses base b) Exp — exponential Power (^) — power (entered as a superscript using Ctrl+^) Sqrt — square root (entered using Ctrl+@) Degree (°) — constant for converting to degrees      N — numerical evaluation to any precision FunctionExpand — expand in terms of simpler functions or smaller arguments FullSimplify — apply full symbolic simplification Series — series expansion TUTORIALS Arithmetic Elementary Transcendental Functions Numerical Mathematics in Mathematica MORE ABOUT Arithmetic Functions Mathematical Functions RELATED LINKS Demonstrations related to Elementary Functions (The Wolfram Demonstrations Project)
