    Thanks you good sir, funnily enough this problem was the exact same and my hw problem. Hope I carried over the knowledge. But I made sure to do the steps you mentioned before you did it and checked if I was good. So I think I'm good XD

    have a question here, I'm looking for a solution in three dimensional since I study programming not sure how to find Z-axis. would you please to point me into right direction ? e.g. article with some example like yours will be great.
    Thanks for the video, your step are very clear, even tell me the correct step before the trick that's very helpful.

    6:41 Why exactly do you need to be within the domain of the radical which is the distance? Within what is inside the radical or the whole radical itself?

    What if the question requires the closest point and the furthest point. How would the answer be different from this one?

    • @crowsmathclass
      @crowsmathclass  2 роки тому +2

      It would be impossible to find the furthest point. The graph continues forever.

  • @katlegolebelwane3318
    @katlegolebelwane3318 2 роки тому

    I got a question that read: find the points on the curve y= √x, [0, 3] that are closest to and furthest from the point (0, 2).

  • @XxRespawNxX619

    Thank you for the step by step process ! When doing this, I set d^2 = (x-3)^2 + (y-0)^2 , and when taking the derivative just set d^2 to 0. I reached the same answer. Is there a particular reason why we do it the way shown in the video, and not just the easier way, as in my comment ? Thanks for any replies in advance.

    • @crowsmathclass
      @crowsmathclass  3 місяці тому

      It will work on this. When you take the derivative of d the part under the square root will end up in the numerator which you set equal to zero
