The function provides the tangent of the input value, i.e.
x1
is the angle the tangent of which is calculated.
Parameter
Select
is used to adjust, if the angle is provided in degree of angle [°] or in radian.
For calculation clarity the argument range is limited to the 1st or 4th quadrant (-90° ... 90° or -

). If input value
x1
is out of this range, output

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

y1
= 1,73205
Example radian:
y1
= tan(
x1
)
x1
= 1,53rad
