Computes sine of the input column. Supports Spark Connect.
For the corresponding Databricks SQL function, see sin function.
Syntax
Python
from pyspark.sql import functions as dbf
dbf.sin(col=<col>)
Parameters
Parameter | Type | Description |
|---|---|---|
|
| target column to compute on. |
Returns
pyspark.sql.Column: sine of the angle, as if computed by java.lang.Math.sin()
Examples
Python
from pyspark.sql import functions as dbf
spark.sql(
"SELECT * FROM VALUES (0.0), (PI() / 2), (PI() / 4) AS TAB(value)"
).select("*", dbf.sin("value")).show()
Output
