week 8

This week I learned something about big-oh. Some proof about W_IS is hard. And we got the definition of O(f). it is also hard to find multiplier C and breakpoint B. we need lots of practice. My group finished the assignment 2 on the weekend. The proof of claim 1.2 is really similar to the proof of the limit of a function by using epsilon and delta. The proof of claim 1.2 may be the most difficult one. By drawing a picture of the function of the floor of x, it is easy to get the proof.
