Trigonometric Functions
All of the functions in this section either take an angle as an argument or return one as a result. In both cases, the units of the angle (radians or degrees) are controlled by the setting of the relevant stream option.
| Function | Result | Description |
|---|---|---|
| arccos(NUM) | Real | Computes the arccosine of the specified angle. |
| arccosh(NUM) | Real | Computes the hyperbolic arccosine of the specified angle. |
| arcsin(NUM) | Real | Computes the arcsine of the specified angle. |
| arcsinh(NUM) | Real | Computes the hyperbolic arcsine of the specified angle. |
| arctan(NUM) | Real | Computes the arctangent of the specified angle. |
| arctan2(NUM_Y, NUM_X) | Real | Computes the arctangent of NUM_Y / NUM_X and uses the signs of the two numbers to derive quadrant information. The result is a real in the range - pi < ANGLE <= pi (radians) – 180 < ANGLE <= 180 (degrees) |
| arctanh(NUM) | Real | Computes the hyperbolic arctangent of the specified angle. |
| cos(NUM) | Real | Computes the cosine of the specified angle. |
| cosh(NUM) | Real | Computes the hyperbolic cosine of the specified angle. |
| pi | Real | This constant is the best real approximation to pi. |
| sin(NUM) | Real | Computes the sine of the specified angle. |
| sinh(NUM) | Real | Computes the hyperbolic sine of the specified angle. |
| tan(NUM) | Real | Computes the tangent of the specified angle. |
| tanh(NUM) | Real | Computes the hyperbolic tangent of the specified angle. |
