    2 hours. My Teacher takes two hours to drag this bullshit along and this got me through half of the homework in ten minute. Every college student appreciates what you do. Thanks so much.

      Agreed, my teacher takes 50mins to just do a bunch of work and talk about it but never explains it. He assumes we already know it like he does.

      I hear this so often, and I reckon the reason is that when we listen to videos such as these we are more often than not alone, and therefore have few distractions ( such as a knock- out good looking lass as we watch and take notice of her ass in class, rather than the Math ).
      Observe that most very able Mathematicians work alone. `Just a thought !

    • @missthalia1850
      @missthalia1850 7 років тому +2

      why did he multiply by root x +3

    • @Ponder217
      @Ponder217 6 років тому +2

      Missthalia18 You probably don't need this info by now haha, but for whoever else needs it: like he said in the video, he multiplied by 1, but he wrote it in a different form. The reason why he chose THAT form (square root of x + 3 divided by square root of x + 3) is because it is the conjugate of square root of x - 3. He is then left with x minus 9 on top, allowing him to cancel the x minus 9 on the bottom. It wraps up the problem into a neat little bow, once you understand how to get to that point. I've done five levels of college math up to now calculus 1 and didn't understand the concept of why you should multiply by the conjugate until just now smh.

    This guy is the best!!!.....I have taken 3 classes of 1hr and 20 mins each an still barely understood what the teacher was teaching and this guys too less than 10 mins to explain half of what the teacher thought....excellent!!!.....the greatest....thank you!!

    your videos have really helped me out so far in my Calculus class. my teacher basically copies what's in the book onto the board, and doesn't really explain anything so i am only able to solve 3 of the 30 problems. your vids help me with the other 27 =)

    • @liamhoward2208
      @liamhoward2208 5 років тому +1

      Math classes are teaching you theory and techniques to solve problems. After awhile you will be able to look at an equation, see the pattern, and know what type of problem it is. Then if you are going into a scientific or mathematical field of work you then have to learn how to apply it. Meaning in the real world those X’s and Y’s all have real meaning to them. For example:
      A very simple business application would be if you wanted to know the economic profit of your competitor and you didn’t know how much he could be charging for each unit but you know everything else:
      Total revenue -(explicit costs + implicit costs)
      We know that revenue is calculated by
      Quantity x Price= 10x
      So,
      10x - ( 400 + 500 ) = 10,000 (economic profit)
      Solve for x
      10x - 900 = 10,000
      10x = 10, 900
      X (amount charged per unit) = $1,090
      Furthermore, if you know how to apply algebra you can figure out any unknown quantity with very limited information.
