https://www.w3.org/Bugs/Public/show_bug.cgi?id=28923 Bug ID: 28923 Summary: [FO31] editorial: math trigonometric functions Product: XPath / XQuery / XSLT Version: Candidate Recommendation Hardware: PC OS: Windows NT Status: NEW Severity: normal Priority: P2 Component: Functions and Operators 3.1 Assignee: mike@saxonica.com Reporter: debbie@saxonica.com QA Contact: public-qt-comments@w3.org 1. The wording for the summary of math:sin "Returns the sine of the argument, expressed in radians" is a little ambiguous - i.e. whether the second half of the sentence refers to the argument, or the returned result. See also math:cos and math:tan. 2. The results for the 4th and 5th examples of math:sin should say "(approximately)" (like the 6th example). Similarly the 6th example of math:cos. 3. The rules for math:asin say: "Otherwise the result is the arc sine of $θ, treated as an angle in radians,..." - Firstly the argument is $arg not $θ. - Secondly, either remove the part which says "treated as an angle in radians", or the wording should be rearranged to avoid the ambiguity of my first point, e.g. "Otherwise the result is an angle in radians, which is the arc sine of $arg,..." Similarly, for math:acos and math:atan. 4. In the last note for math:asin, replace $θ by θ in the given range. Similarly, the last notes for math:acos and math:atan. 5. The results for the examples of math:atan2 use math:pi, but the other trigonometric functions use 3.141592653589793e0 (approximately), etc. Should these actually be the same? -- You are receiving this mail because: You are the QA Contact for the bug.Received on Tuesday, 7 July 2015 15:14:20 UTC
