    • Hints for the First Question of Homework 1

      Posted on March 14, 2024 · 1 minute read

      Let’s apply what we learned in Calculus 1 to the first question of this homework. Given a function $f(x)=x^3$ and $x_0=100$, we want to estimate the relative error of $f(x_0+\Delta x)$, given that the relative error $\frac{\Delta x}{x_0}$ is less than $1\%$. What we need to do here is to... [Read More]
