dbf.sin(col=<col>)

Parameters

Parameter	Type	Description
col	pyspark.sql.Column or column name	target column to compute on.

Returns

pyspark.sql.Column: sine of the angle, as if computed by java.lang.Math.sin()

Examples

from pyspark.databricks.sql import functions as dbf
spark.sql(
    "SELECT * FROM VALUES (0.0), (PI() / 2), (PI() / 4) AS TAB(value)"
).select("*", dbf.sin("value")).show()
