Calculus Section 1.7 I went over your notes. I read the notes by the late James Stewart and still I am lost. This is a tough section, to say the least. So, I will work on showing that a limit exists using the Delta-Epsilon Definition of a Limit. This is all I am going to do in terms of this section. That in itself is hard for me. I may post a few more questions from Section 1.7 for you to solve entirely. For example, can you please work out number 4 showing steps as you go along the way? Thank you. [ATTACH=full]2712[/ATTACH]
