when you were little was additon the hard part of multiplication? If so you can relate
so I took my first calc 4 test today and I actually knew all the concepts which relate to calc 4. However, I was not able to realize dat domain of Ln(9-x(squared)) was (-3,3) not [-3,3]. Now since I for one dont like Ln I decided to think of it as a square root,one would think with was smart, atleast I did lol, but I forgot to realize one simple difference the square root of zero does exist where as the Ln of zero doesnt exist. With was by far the easiest question ever but I managed to get it wrong . . . also I toally forgot about arctan(x) I actually wrote it down but erased it because I said o myself and I quote, "there no way its just arctan(x) its got to be some crazy thingy" . . . but to my surpise along with your surprise(you the reader) . . . it was the right answer :'(

Congratulations to you Yuri. I am so happy that one of us is understanding all of this stuff. I think you might want to put in a graphic each time you insert a prompt. In that way your photo will go with what is being written on the right. If you go to Google Images you can find some funny images about math. In the meantime, try some new gadgets on your blog. You could add music, videos, lists, links etc. Please check your spelling each time you post something. I am delighted to be reading about what you are doing each week. Keep up the good work Dr. Ries
