arctan(
arctan(
VALUE
)
The arctan( function calculates the inverse tangent of a numeric value.
Parameters
This function has one parameter:value – a numeric value.
Description
This function calculates the inverse tangent of a value. The graph below shows the result of the arctan( function given input values from -5 to +5.
The output of the arctan( function is an angle. This angle is normally in radians, but in a procedure you can tell Panorama to switch to using degrees instead, like this:
degree
NewAngle=arctan(value)
The degree statement tells Panorama to use degrees instead of radians in all trigonometry calculations. Panorama will continue to use degrees until the end of the procedure, or until a radian statement is encountered.
