Example degree of angle:
y1= arctan(x1) x1 =1° = y1=45
Example radian:
y1= arctan(x1) x1 = 12rad = y1 = 1,488

culated. Parameter Select is used to adjust, if the angle is provided in degree of angle [°] or in radian.
The calculation is output in degree of angle [0° ... 180°] and in radian [0 ... ó].
Example degree of angle:
y1= arccot(x1) x1 = 45° = y1 = 1,273
Example radian:
y1= arccot(x1) x1 = -12rad = y1 = 3,058
