Happy, this week i have learned the limit in terms of the definition and how to use it to proof the limit is correct. Firstly i feel a little bit harder for me, because i failed to understand the examples in English.But at last i get the help from instructor and peers. That’s fantastic . I can finish most of my homework and understand the core of it. My first week math learning in UBC is difficult but unforgettable as well as valuable. xD
