Returns the tangent of val.



Argument Description
val The angle (in radians) to return the tangent of.

Returns: Real


In a right angled triangle tan(val) = Opposite / Adjacent where val is one of the three angles.

NOTE: The value returned is in radians, not degrees.

Note: Pi/2, (3 pi/2), -pi/2 and a vast number of other values will error with this function due to their returning infinity, a graph representation of this would produce asymptotes at these values.


val = tan( pi );

This will set val to 0.
