Talk:Multiple Angle Formula for Tangent

A few things:
 * $\N$ is by default greater than or equal to zero, so $\ge 0$ is unnecessary.


 * The $n = 0$ case should probably be taken completely separately, as it is a degenerate case. So recommend you go back to treatment of the cases $n = 1$ and $n = 2$.
