[chriswilliams]

Once again you have helped me complete a difficult chapter from openstax. Thanks for doing what you do.
Btw what did you do to get so good at math? I practice a lot but there are times when I am just at a total loss and if the answers cannot be found online I am just stuck not knowing how to solve some of the more difficult problems.
