The Formula Node enables you to enter values in degrees as well as in radians. On the **Attribute Manager**’s Node Properties page, choose the system you want to use — radians or degrees — using the Angle Type drop‑down list.

By checking the Use Portnames check box, you can use the actual input port names of the Node

In addition to basic math operations, you can use functions such ass COS (cosine), SIN (sine), SQRT (square root) and EXP (Exponential function) as well as constants such as Pi. For a list of all operators, functions and constants, see the Appendices of this manual.
