Definition: | atom x2 = tan(atom x1) |
Description: | Return the tangent of x1, where x1 is in radians. |
Comments: | This function may be applied to an atom or sq_tan() to all elements
of a sequence. The rules for
sequence operations apply.
Note that the following diagram uses degrees, ie tan(30*CD_DEG2RAD) = 0.577, where CD_DEG2RAD is defined in pGUI as PI/180. ![]() |
Example: |
t = tan(1.0) -- t is 1.55741 |
