Hello!
Someone else has already compiled solutions to all exercises in Tom Apostol's "Calculus", but on for vol. 1. As I am taking multivariable calculus this semester, I've decided it would be beneficial (as a study tool) to publish my solutions online to the second volume. Apostol provides basic solutions, but I thought I'd expand on his.
This is a very big project. I expect it to take about a year. I will be updated my Steemit page as I get further and further along.
Here a few links:
Vol. 1 solutions: (single variable calc)
RoRi's Solutions to Volume 1 on his blog Stumbling Robot (opens different site)
Vol. 2 solutions: (multivariable calc)
My ongoing solutions to exercises 1.5 (opens a steemit page)
My "master" page for all solutions, very much incomplete (steemit page)
Although my solutions are very incomplete so far, I would love criticism on my proofs that I have. You can find everything from these links. If you need help getting access to the PDFs for these books, send me a message.
