sin_rad¶
Description¶
Computes the sine of the input and returns a float64. The input should be expressed in radians.
Arguments
- angle (required) Angle in radians, a float64 
Return type¶
float64
Domain¶
This is a scalar function (calculates a single output value for a single input row.)
Categories¶
Usage¶
sin_rad(angle)
| Argument | Type | Optional | Repeatable | Restrictions | 
|---|---|---|---|---|
| angle | float64 | no | no | none | 
Examples¶
make_col sin:sin_rad(angle)
Create a column ‘sin’ with the result of the sine of column ‘angle’ The resulting column will be in radians.
Given the below column angle, sin_rad produces the below column sin
| angle | sin | 
|---|---|
| 0 | 0 | 
| π / 4 | √2/2 | 
| π / 3 | √3/2 | 
| π / 2 | 1 | 
| π | 0 | 
| 3π / 2 | -1 | 
| 2π | 0 | 
make_col sin_pi:sin_rad(pi())
Create a column ‘sin_pi’ with the result of the sine of pi. sin_pi will be 0.
