Rainbow Road (Maths Appendix)

This is a reupload of Rainbow Road (Maths Appendix). I'm shutting down my old account and reuploading everything here in order to better manage my music. I'm going to send a notification to all my followers on that account that mentions this information and lets them know to subscribe to this account instead. To those of you already subscribed to both accounts, make sure to unsubscribe to my old account! Only when I have zero followers left there will I delete the account completely.
