## Solutions to Real Analysis: A Long-Form Mathematics Textbook Chapter 3

Exercise 3.1 Solution: Let $\e=0.001$. Because $(a_n)$ converges to $0.001$, there exist $N$ such that for all $n> N$ we have$|a_n-0.001| < 0.001,$$\Longrightarrow -0.001 < a_n- 0.001 < 0.001,$\[\Longrightarrow 0<…

Exercise 1.8 Solution: (a) Because $a < b$, we have $b-a\in P$. Similarly, we have $d-c\in P$. We have\begin{align*}(b+d)-(a+c)&=b+d-a-c\\ \text{ by Axiom 6 (a)} \quad&=(b-a)+(d-c)\in P.\end{align*}Hence $a+c < b+d$. (b)…
