In this week, we have been introduced to the concept of limit and its mathematical symbol. In our lecture notes, we demonstrated using limit to analyze the order of growth for functions in algorithm analysis (on slides 21 and 22). Please explore a bit more into algorithm analysis, and list 3 to 5 concepts/methods where the notion of limit is used. In your opinion, can any of these concepts/methods be accomplished in ways other than limits? Why or why not?
