Tangent & Cotangent Graphs w/ Transformations

I do two examples of Tangent and Cotangent that include multiple transformations with a t-table. This video has two errors noted below which have annotation corrections in the video which you will see if you have Flash.

At minute 7:27 I say that the cot(0) is -1/0, that should be 1/0.

The very last point I mention at around 10:42 should have a y coordinate of -1 not 0. Sorry for the small errors:)
