I noticed than in the chapters I am studying now that while they give us a formula for taking the derivative of log base a of x, I can't find a correspoding formula for finding the integral of log base a of x. We have a table of integrals in the back of the book, but I only see integrals pertaining to forms of ln x. So.. am I missing something? Does it not exist? Is it something so ugly I don't even want to know about it?? Thanks!
