----------------------------------
Summary: Errors in trig function descriptions
Key: DRILL-6073
URL: https://issues.apache.org/jira/browse/DRILL-6073
Project: Apache Drill
Issue Type: Bug
Components: Documentation
Reporter: Paul Rogers
Assignee: Bridget Bevens
Priority: Minor
The documentation contains a [Math and Trig
|http://drill.apache.org/docs/math-and-trig/] page. Information about the trig
functions are wrong.
{{asin\(x)}}, {{acos\(x)}}, {{atan\(x)}}: text: "Inverse sine/cosine/tangent of
angle x in radians". But, of course, an inverse function produces radians as
output, and takes the sin/cos/tan value as input. This, the value "x" is not an
angle in radians, it is the sin/cos/tan value to be inverted.
{{SINH()}}, {{COSH()}}, {{TANH()}}: these each take an input, but the
placeholder "x" is not shown, incorrectly suggesting that they take no argument.
List of functions: The list of non-trig functions earlier on the page is in the
form of a table. For symmetry, the list of trig functions should also be a
table, not a bulleted list.
