    at 6:00 I think x^2 = 4 gives x = + or - 2 instead of sqrt of 2

    great lesson... is there a way to do it 9 ways with a solid bounded above z=x+y-2 and below z=0? I know how to do 6 from your lesson, is there 3 more ways... I was thinking of splitting the solid in 2 and triple iterate the integral with half the solid... I know I am looking at an isosceles triangle, if I am looking above the solid.

    Though this video is very useful, this method can be applied only when its possible to form such a table. But look at this question : Find the volume under the surface x+2y+z=4 and above the circle (x^2)+(y^2)=4 in the xy plane. It's not possible to form the table in this case. Thank you as it has helped me to solve questions where I can form the table of limits.

    @sushantbhatta7759 8 ปีที่แล้ว

    wow i just loved the way you explained without a graph. I just have a question; what if there was y^2 in the equation instead of y. You would get two values of y from the equations and have 0 as given values so what will be the limits. And also if y was equal to something else say 2 instead of 0 would we still be substituting the value of y as 0 in the equation or should we consider 2 instead? please reply . thank you

    • @kristakingmath
      @kristakingmath  8 ปีที่แล้ว

      +Sushant Bhatta If you had y^2, then you probably wouldn't be given y=0, so you'd use those two original values.

  • @saloksingh7
    @saloksingh7 ปีที่แล้ว

    Hi there. I have a similar question but the limits are defined by y^2 + z^2 = x and plane x=4. When finding the y(z) and z(y), we get y=√-z^2 and z=√-y^2 which is giving imaginary numbers. How would we proceed for such a problem?

    @qualquan 2 ปีที่แล้ว

    A soul less tour de force. Ought to explain at the outset thar 1) first we write an equation of one side expressed in terms of the other 2 sides.
    2) we then integrate this equation (of the first side) over the next side to get an area and express them in terms of the 3rd side.
    3)Finally we integrate this area over the 3rd side between definite limits to get a definite integral representing a numerical volume.
