      Sometimes many profs are impatient they always need to finish everything before the semester is done in 2 weeks
      That's why integralcalc and many others are there

  • @MrYaseen100
    @MrYaseen100 8 ปีที่แล้ว

    Great vid! How did you know to choose from the right side of the graphs? What i mean is after you drew all the lines and stuff in 4:15 you shaded the right side...would it have made a difference if you shaded the left?

    • @kristakingmath
      @kristakingmath  8 ปีที่แล้ว +2

      +Yaseen El-Idrisi It wouldn't have made a difference, and you could definitely shade the left side if you wanted to, but when you're defining the region, it's a lot easier to work with an area that's inside the first quadrant than any other quadrant, because all the boundaries are going to be defined by positive numbers. So if you want to make it easy on yourself, and you can pick a region that's in the first quadrant, I would definitely do so. I hope that helps!

    When you rotate about the y axis and the function is x=2sqrt(y) so I always need to change the x to y? Also, does this apply to the other way around where you rotate about the x axis and if you are given the function as, say, y=3x-2, you need to convert it to y?

    hi , can somebody help me with this question ? -> Find the volume of the solid formed by revolving this region bounded by the graphs of x=〖y〖(1- y^2)〗^(1/4)〗⁡, y=0, y=1 and x=0 about the y-axis. hope you can help me asap ..

  • @egmaalouf
    @egmaalouf 9 ปีที่แล้ว

    I found a way correct me if I am wrong
    We can look at the axis of rotation of the if the axis is x-axis then the boundaries should be y= and y=
    Second we look at the shape and directly apply the formula
    integrate plug in the numbers and the solution is done
    I used to conflict in these but I made many problems allowed me to think of this way to get it
