This example illustrates how to apply basic trigonometric functions to your transformations. All of the functions take inputs in radians.
Source:
In the following sample, input values are in degrees:
| X |
|---|
| -30 |
| 0 |
| 30 |
| 45 |
| 60 |
| 90 |
| 120 |
| 135 |
| 180 |
Transformation:
In this example, all values are rounded to three decimals for clarity.
First, the above values in degrees must be converted to radians.
