I think there is a mistake with the scaling on the graph.

-pi/8 + pi/4 = pi/8

pi/8 + pi/4 = should be 3pi/8 not 5pi/8 as shown in the vid.

9pi/8 seems wrong as well.

If I'm missing something let me know!

Ba ho,
Actually you are correct.  The period for the tangent function is  (Pi/B).

I left the general equation on the board but I should have changed it for the tangent function.
