Domain-specific

• Inverse Trigonometric Functions
  • General inverse trigonometric functions are multivalued; principal branches are made single-valued by cuts in the complex plane, and formulas such as principal \(\arcsin z\) involve chosen square-root and logarithm branches.
• Principal Value
  • The NIST Digital Library of Mathematical Functions treats the logarithm, general powers, inverse trigonometric functions, and inverse hyperbolic functions by explicitly separating general values from principal values and declaring their cuts.
