[jira] [Created] (CALCITE-5599) Support more trigonometric functions for BigQuery

Zou created CALCITE-5599:
----------------------------

             Summary: Support more trigonometric functions for BigQuery
                 Key: CALCITE-5599
                 URL: https://issues.apache.org/jira/browse/CALCITE-5599
             Project: Calcite
          Issue Type: New Feature
            Reporter: Zou


We have already supported many trigonometric functions in calcite, such as SIN, COS, and there are still some trigonometric functions in BigQuery not supported：
 * ACOSH(X)：Computes the inverse hyperbolic cosine of X.

 * COTH(X): Computes the hyperbolic cotangent for the angle of {{{}X{}}}, where {{X}} is specified in radians.
 * CSC(X): Computes the cosecant of the input angle, which is in radians.
 * CSCH(X): Computes the hyperbolic cosecant of the input angle, which is in radians.
 * 
SEC(X): Computes the secant for the angle of {{{}X{}}}, where {{X}} is specified in radians. 
 * SECH(X): Computes the hyperbolic secant for the angle of {{{}X{}}}, where {{X}} is specified in radians.

More info could be found in [BigQuery Doc|https://cloud.google.com/bigquery/docs/reference/standard-sql/functions-and-operators#acosh]

This is an umbrella issue, and I will create subtasks for each function listed above later.
