Nice textbook

I am using the introduction to analysis textbook for my advanced calculus course this semester.. The author is the BEST I have ever seen... haha just saw this in my assignment:

Exercise 12.4
Hint: prove the following claims:
a) blah blah
b) blah blah
c) blah blah
then refer to exercise 9.9 c)

So I happily turned to 9.9 c), and I saw this,

To prove this theorem, you have to consider 3 cases...
Case 1: Please refer to Theorem 8.2
Case 2: Please refer to Theorem 8.3
Case 3: Please refer to Exercise 8.9

so...

I turned to Theorem 8.2, and I happily found "this theorem is built on Theorem 4.6... "

and Theorem 8.3 happened to be an extension of Theorem 7.8

and to solve Exercise 8.9, "please refer to page 42..."

......

This hint is quite helpful man!!! Help me revise the whole book for this proving question... I do not dare to continue with theorem 4.6, 7.8 and page 42... Later I might be asked to refer to the wikipedia for blah blah and this might never come to an end!!!!

Argh!!!

People have asked me why my name is so damn bloody hard to pronounce, I would say it's not my problem. Just in case anyone who is interested to find out what the name actually means, here it is:

萱 pronounces as xuan, is the flower called daylily pictured above;

仲 pronounces as zhong, means I am the second child in the family

弦弦诉人意,弓弓道世情

可以高贵,可以平凡
可以不问英雄出处
可以痴情风流的二胡
一弦可以大江东去
一弦可以月游西湖
一曲未了竟有琴弦启开江南
让俏丽的姑娘
用浓浓的茉莉花语
从红袖里伸出酥手
把一个河山香透

My Erhu, My Forever Love
