The function provides the arcus sinus of the input value, i.e. x1 is the angle the arcus sinus of which is calculated. Pa
-
rameter Select is used to adjust, if the angle is provided in degree of angle [°] or in radian.
The calculation is output as degree of angle [-90° ... 90°] or as radian [-

validity range, output y1 is limited to -1,5 w 10

(x1>1 ).
Example degree of angle:
y1= arcsin(x1) x1 = 0,5° = y1 =30
Example radian:
y1= arcsin(x1) x1 = 1rad = y1 = 1,571
