Same ol', same ol': Pick x-values. Plug them in. Draw the dots. :wink:

(Since you already know that $-\frac{\pi}{2}$ and $\frac{\pi}{2}$ are asymptotes for the "regular" tangent curve, you might find it helpful to set the argument, $\pi x$ equal to these values. Then solve for the x-values that correspond to the asymptotes for this particular tangent curve. And so forth.)
