Some of you have sent an email with a link to a video. You need to also include a description of the question you are solving in the email. If you are solving a problem from the book, don’t just say “homework number 32” – also describe the question. I don’t always have the book with me.
If you did this for the first video, you resend an email with both the question and the link to the video (also which standard this is for).
