- TL;DR Summary
- I am reading A Course in Mathematical Analysis Volume 1 by D. J. H. Garling, and I am having trouble in the following demonstration of Section 2 Differentiation. part 4 of the test, the first part of the second inequality does not make sense, I do not understand its justification. I hoped they can help you understand the inequality, or how to do the test correctly, as this seems like a Garling mistake.
