tan(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.
