Exercise 1.1: Prove that the set of rational numbers is dense in the set of real numbers. To help students overcome these challenges, we will

Exercise 2.1: Prove that the sequence $1/n$ converges to 0. Our goal is to help students better understand

Solution: Let $x_0 \in \mathbbR$ and $\epsilon > 0$. We need to show that there exists $\delta > 0$ such that $|f(x) - f(x_0)| < \epsilon$ for all $x \in \mathbbR$ with $|x - x_0| < \delta$. Choose $\delta = \min)$. Then for all $x \in \mathbbR$ with $|x - x_0| < \delta$, we have $|f(x) - f(x_0)| = |x^2 - x_0^2| = |x - x_0||x + x_0| < \delta(1 + |x_0|) < \epsilon$, which proves the result.
