The SageMath package for computations with error terms with explicit estimates including a (monomially bounded) dependent variable, https://github.com/behackl/dependent_bterms, has received a hand full of useful updates since its first appearance at AofA2024. In this brief talk / workshop, we give a short hands-on introduction to the tools shipped with the package and illustrate how the new features can be used.

Joint work with Stephan Wagner.
