    I am struggling with math so much It’s pushed my graduation date back. I am an accounting major, but I have to pass pre-calculus after a few years hiatus. It’s my second time taking the class and I have to get a B+ or else I get dropped from the program at my school. I’ll be using your course to hopefully understand more.

  • @professorfernandohartwig

    Great lecture as always! I just wanted to mention that I think it is a mistake to say that f(x)>=g(x) is sufficient for convergence of f(x) to imply convergence of g(x). As one of the students asked, it is possible that g(x) is not bounded below while f(x) is, so f(x) could converge while g(x) could diverge towards negative infinity. For example, consider f(x) = 1/x^2 and g(x) = -x^2 and the interval from 1 to infinity. Clearly, f(x)>=g(x) in this interval. However, g(x) is not convergent even though f(x) is. Hope this helps other viewers who may have gotten a little confused about this.
