Sorry but I'd like to er...ask a question in this thread if you don't mind cos i didn't want to make another thread about it lol. Um, I know that topics that weren't covered in lecturers we shouldn't worry about, but how about examples from the textbook that are different from examples from the lecture notes? Like for eg, With the functions intro , the lecturer note only gives egs on how to simply a composite as a function but in the textbook, they have other things such as how to express a function as a composite? Hence, should we be making note of these extra materials as they could be covered? Ie. not follow too strictly on the lecture notes?
