1 | Returns the hyperbolic tangent of the specified angle. | |
2 | Computes the tangent of the specified argument (in radians. | |
3 | Most of us can' t tell our secant from our cotangent. | |
4 | And you know this is just what sine, cosine, and tangent are. | |
5 | Note that this code calculates the tangent each time- this is only for clarity. |
