Homework Statement


The solid enclosed by the paraboloid x=y2+z2 and the plane x=16.


Homework Equations


Triple integral in ractangular coordinates


The Attempt at a Solution


I figured out this is a paraboloid that circles the x axis, that starts at the origin and it gets wider and wider as it goes in the x direction until it is stopped by the plane x=16 where there is a circle around the x-axis with a radius of

[tex]\int_{x=y<sup>2</sup>+z<sup>2</sup>}^{16}\int_{z=-\sqrt{16-y<sup>2</sup>}}^{\sqrt{16-y<sup>2</sup>}}\int_{z=0}^4 dxdzdy[/tex]

I was just curious if my set up looks right.

Thank you.

ok that is not what I meant to write lol, I have to work on this really quick
 


ok I got what I want up there except for some reason when I try and square stuff, the coding keeps appearing for the stuff in the integrals but not in the first sentence I wrote.
 


In TeX, you use ^ to get a superscript and _ to get a subscript, so x2 would be written x^2 and xmin would be written x_{min}, for example.
 


The integral isn't correct.
Your left-most integral bounds shouldn't have variables in it.
Your right-most shouldn't have constants.
You have used "z=" in two of the integrals, and "y=" in none.
 


You have the integrals backwards, and I assume where you wrote z=0, you meant y=0. You have dy on the end, so its limits should be on the frontmost integral. Similarly, the limits for z should be on the middle integral, and the limits for x on the innermost integral. Other than the wrong order, it looks good.
 


Ya I meant to write them as dxdzdy, but I was so caught up in trying to use Latex for the first time I didn't even notice I had the order mixed up. Thank you for the help.
