dtan(val);
| Argument | Description |
|---|---|
| val | The angle (in degrees) to return the tangent of. |
Returns: Real
In a right angled triangle dtan(val) = Opposite /
Adjacent where "val" is one of the three angles.
NOTE: A vast number of values (90, or -90 for example)
will error with this function due to their returning infinity, a
graph representation of this would produce asymptotes at these
values.
val = dtan(45);
This will set "val" to 1.
