Why is quiz part often harder than content in a maths textbook?I find many problems very very tough to do in Casella's probability textbook, which reveals knowledge not covered in his content. X'(yXβ)=0 #2 20100725 22:15:36
Re: Why is quiz part often harder than content in a maths textbook?Hi George,Y;
Which one?
I am forced to agree. I have seen some where the problems are undoable even if you are familiar with the chapter. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20100725 22:40:08
