The Inverse Cotangent Function

I have removed all annotations from my videos that were used to correct errors (YouTube is getting rid of Annotattions) Any errors in the videos have been corrected in the NOTES. If you have already subscribed, you can use your User Name and your Password to download the NOTES in a MS WORD FILE. or a PDF FILE.
