About

It is my aim to post on this website neat, detailed solutions to as many problems in textbooks of mathematics, science, and engineering that I can get a hold of. The solutions will be available for free as PDF files. University students, scholars, and independent learners around the world will undoubtedly find this website to be a valuable resource. My work here is dedicated to the future generations of mathematicians, scientists, and engineers.

Follow me on Twitter if you wish. I'll only use it if there's an emergency.

The STEM Textbook Index

In the "STEM Book Index" section all of the textbooks that I have written solutions for are listed alphabetically by the primary author's last name. The latest edition of each book will be used, but if there happen to be more problems in an earlier edition, I will post them as well and note the edition. Exceptions will be made for the books by Churchill and Boyce and DiPrima because some problems were deleted in the latest editions.

For every problem a statement and solution are provided. The point of this is so that you have a chance to solve the problem on your own before looking at the solution. Note that problem-solving skills are not developed by reading solutions alone, much like how watching Michael Jordan play basketball won't make you a better basketball player. Nevertheless, when you are forced to solve problems in a limited amount of time, they can be really helpful. I try to explain what I do and why as simply as possible to help those trying to learn.

I post everything I write to this website. There are no hidden solutions, and nothing is placed behind a paywall. If you don't see a solution for a problem here, it's because I haven't written it yet. Please be patient. Some people have asked me what software I use. Here's a list.

  1. Notepad++
  2. TeXworks (MiKTeX 2.9)
  3. Microsoft Paint
  4. Wolfram Mathematica

Help Support the Website

I started this website to tutor people around the world as a business. Due to a lack of customers, though, the business failed. The website is now essentially a charity whose aim is to help educate and inspire students. If you wish to make a donation, you may do so by any of the payment options under the "Support" tab. I say, "charity," but know that it's unofficial; donations to this site will not count as tax-deductible expenses. Every penny goes to keeping this website up longer and allows me to spend more time writing. Those of you who have donated to my cause have my sincerest thanks. You know who you are.

There is a Patreon account also, so if you would, please become a monthly subscriber. You can be one for as little as $1 per month. There are no benefits to being one, but you can say you support a tremendous educational resource on the internet and you help feed the creator.

But please, if you can't afford to, then do not donate. I want to be able to sleep at night.

Contact

This is where I keep documents I gave to help people who contacted me in the past. I'm thinking of turning this section into a blog---something fun and informative for students.

Thank you for reading this.

Sincerely,
The STEM Jock
