The function provides the cotangent of the input value, i.e. x1 is the angle the cotangent of which is calculated. Pa-
rameter Select is used to adjust, if the angle is provided in degree of angle [°] or in radian.
For calculation clarity, the range for the argument is limited to the 1st and 2nd quadrant (0° ... 180° or 0 ... ó). If input
value
x1 is out of this range, output y1 is set to 1,5 w 10 37 ( x1<0) or 1.5 w 10 37 ( x1>180 [x1>ó]).
Example degree of angle:
y1= tan(x1) x1 = 45°
= y1 = 1
Example radian:
y1= tan(x1) x1 = 0,1rad =
y1 = 9,967
