    The UA-cam learning format is exponentially better than any other university learning format. It offers the opportunity to actually UNDERSTAND instead of MEMORIZING the material. With a few mouse clicks A lecture can be repeated until the problem is understood. It can also be paused to gain any necessary background information required to understand each step. Working out the reason for each step can take time, from minutes to days, which would not be possible in a traditional classroom.
    Not only is the educational format better, but many more students can be reached. This particular video, as of 2/1/2017, has 834,351 views. As of now, 3/15/2022, the number of views has to be in the millions. No college professor in any traditional classroom format can come close to lecturing the number of students represented in those views.

    At 1:00, he only adds C to the right side because when you integrate, on the left side there's a c1 and on the right there's a c2. When you subtract c1 from both sides, you get a c on the right side that isn't c1 or c2. I hope this helps, because I was wondering why he did that myself.

    At 4:04 you can't just ignore that its ln |y| and not just ln y. When you substitute e^c for C your new constant C wouldn't include negative numbers since e^c never is negative. BUT if you used |y| it would simplify to ±e^c which includes negative numbers.

    • @cbookins
      @cbookins 2 роки тому

      No. C is simply a number like 5, 21, 100, etc. and e is also just a number 2.72. 2.72 raised to any number is still just going to be a constant, so it is just c.

    • @vez3834
      @vez3834 2 роки тому

      Because e^(ln 5) = 5... it doesn't matter whether you put 5 or e^(ln 5). Thus, we can just mark e^c as c.
      Another way to think about it is that e is a constant and c is a constant. Constant to the power of a constant is itself a constant. So e^c can be rewritten as just c.
      The point of c is not to keep the exact form of whatever you did, but to make make the integration happy. Making it a simpler number makes for easier calculations later.

    1:24 how would that just be considered C? Is that a property? How did he go from 3C to C? Is it because C can be anything? I need an explanation!! Lol

      This is super late but pretty much he just combined the 3 c s into 1 constant C. So c + c + c = 3c = ( the new) C

    How do you know which side to add the plus C?

    Tan(180) and tan(360) also give 0, or every 180 degrees to be precise. So value of c could be 179 and 359 as well.
