Trigonometric Functions
These expression functions allow users to specify trigonometric functions as part of any expression.
NOTE: All trigonometric data are expressed in radians, not degrees.
Trigonometric Functions
For each function below, a is an angle expressed in radians.
| Trigonometric Function | Expression Function |
|---|---|
| cosine | cos(a) |
| sine | sin(a) |
| tangent | tan(a) |
| cotangent | ctan(a) - the reciprocal function for tangent |
Inverse Trigonometric Functions
For each inverse function below, denoted by the prefix “arc”, a is an angle expressed in radians and x and y are one-dimensional signals.
| Inverse Trignonometric Function | Expression Function |
|---|---|
| arcsine | asin(a) |
| arccos | acos(a) |
| arctangent | atan(a) |
| atan2(y,x) - computes the arctangent between two one-dimensional signals; returns a one-dimensional signal |
