    thank you for the calculations, now i finally understand why those two formulae look different but are the same...

    Hi Eddie, your teaching is excellent. Very comprehensive and educational. I try to learn group theory many times, but fail. It is not easy to understand. Can you take this challenge to teach us group theory, it is an important tool for many different areas. Thanks

      Eddie Woo is a high school teacher, so he's unlikely to cover group theory. Try The Math Sorcerer or MathDoctorBob for group theory. Try Socratica or Juan Klopper for abstract algebra. If you don't like those resources, let me know, and I'll provide others. Take care and happy learning!

    at @10:44, u wrote the expected value of x squared as integral of x squared times the f(x). why not f(x squared)? see, if E(x) is a function then E(x squared) should replace x with x squared, shouldn't it?

    Can someone link or share the Reference Sheet that the professor is using?

    Can someone help me with this problem:
    consider Fibonacci sequence: 1,1,2,3,5,......,An
    prove that for all n:
    A(n+1) < (2)ˇn

      You can prove this easily via induction
