A Medical student teaches what he has learned
Thank you for this video! I was having a lot of trouble figuring out how I was meant to answer that question in web assign until I found your site.
To be honest, I didn't know what those symbols meant until last week when it came up in the homework. I have read every page of the chapter and it isn't covered, not once. I had to ask the professor. But I'm glad it helped you out.
