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 [- у /
2
... у /

]. With arguments out of the function
validity range, output y1 is limited to -1,5 w 10 37 ( x1<-1) or 1,5 w 10 37 ( x1>1 ).
Example degree of angle:
y1= arcsin(x1) x1 = 0,5°
= y1 = 30
Example radian:
y1= arcsin(x1) x1 = 1rad
= y1 = 1,571
