11.2 COS (cosinus function)
yx
1
cos 1)= (
The function provides the cosinus of the input value, i.e. x1 is the angle the cosinus of which is calculated.
Parameter Select is used to adjust, if the angle is provided in degree of angle [°] or in radian.
Calculation clarity can be reached by limiting the input signal (e.g. to the 1st and 2nd quadrant (0°...180° /0...ó). Inter-
nal limiting is omitted. If input value x1 is out of the range in which the cosinus function can still provide purposeful
values, output y1 is set to 1,5 w 10

.
Example degree of angle:
y1= cos(x1) x1 = 60° = y1 = 0,5
Example radian:
y1= cos(x1) x1 = 45rad = y1 = 0,525321988
