dtan

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.

NOTE: This function takes a value in degrees not radians

Syntax:

dtan(val);

Returns:

Real

Example:

val = dtan(45);

This will set "val" to 1.
