>>> from pyspark.sql import functions as sf >>> spark.sql( ... "SELECT * FROM VALUES (PI() / 4), (PI() / 16) AS TAB(value)" ... ).select("*", sf.cot("value")).show() +-------------------+------------------+ | value| COT(value)| +-------------------+------------------+ | 0.7853981633974...|1.0000000000000...| |0.19634954084936...| 5.027339492125...| +-------------------+------------------+
Example 2: Compute the cotangent of invalid values
>>> from pyspark.sql import functions as sf >>> spark.sql( ... "SELECT * FROM VALUES (0.0), (FLOAT('NAN')), (NULL) AS TAB(value)" ... ).select("*", sf.cot("value")).show() +-----+----------+ |value|COT(value)| +-----+----------+ | 0.0| Infinity| | NaN| NaN| | NULL| NULL| +-----+----------+
