      This is such a strange lie... it's not possible to fail the first exam and end the class with a 97%. You'd have had to literally get 100% on everything else and the first test would have still had to have been only like 10% of your final grade.

      He has made mistakes in several videos - he just usually catches them, or is corrected by one of the students.
      And this actually makes him more human, instead of those robot teachers who pretend like they never ever make mistakes.

      *TIP:* In Calculus 3, these concepts will be extended to find the area between 3-D surfaces and 3-D objects.

    • @taekwondotime
      @taekwondotime 4 роки тому +1

      TIP: @36:00 It helps to separate the constants from the variables when you go to evaluate the integral. For the first term in the integral, begin by writing 1/2 x^2 instead of x^2/2. That way you can pull out the 1/2 and be left with evaluating 3^2 - (-2)^2 which is much easier. You get 9 - 4 which equals 5 and then you multiply by 1/2 to get 5/2. Every time you see a constant, get rid of it before plugging in your bounds to evaluate and you'll make the math a whole lot easier and save yourself from doing the same work over and over again. :)

    Dear Brofessor Leonard,
    I'm on summer break between Calc 1 and Calc 2 and I've been going through your lectures of both. It's wonderful that you never assume that your students know things. You've cleared up so many random areas of confusion about logarithms, exponent rules, trig/inverse-trig, properties of this or that thing, all while watching videos that weren't even covering that topic.
