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

Example degree of angle:
y1
= cos(
x1
)
x1

= cos(
x1
