another tricky bonus question...

OpenStudy (anonymous):

\[\int\limits_{?}^{?}\int\limits_{?}^{?}\int\limits_{?}^{?} dv\] set up the integral in the following order dv=dxdydz. then, find the region.

OpenStudy (anonymous):

that IS the complete question and i have the answer but don't know how it's solved.

OpenStudy (mathteacher1729):

Without limits or the function to be integrated... there's not much to do here.

OpenStudy (anonymous):

no

OpenStudy (anonymous):

i will post later, gotta get ready for an exam that starts in an hour. check back later please.

OpenStudy (anonymous):

luckily i won't need it for the exam, it's a bonus no one was able to get anyway

OpenStudy (anonymous):

don't worry, you will never see this after final

OpenStudy (anonymous):

diff eq?

OpenStudy (anonymous):

thought i need calc II for diff eq i'm taking next

OpenStudy (anonymous):

calc III

OpenStudy (anonymous):

m\[\int\limits\limits_{0}^{1} \int\limits\limits_{-\sqrt{1-z}}^{\sqrt{1-z}} \int\limits\limits_{y ^{2}}^{1-z} dxdydz\]

OpenStudy (anonymous):

that's answer?

OpenStudy (anonymous):

and then integrate but i have no idea where the limits come from

OpenStudy (anonymous):

x(1-z)-x(y^2) then integrate with respect to y, then z

OpenStudy (anonymous):

where did you did the limits from ?

OpenStudy (anonymous):

that's the answer. don't know how you get it

OpenStudy (anonymous):

If you can take picture of actual problem, maybe I can figure it out

OpenStudy (anonymous):

it's the exact question what i wrote. no limits. just has "D" under the 3 integrals.

OpenStudy (anonymous):

to indicate region, i thought

OpenStudy (anonymous):

they might have left it out by mistake

OpenStudy (anonymous):

i don't think they did

OpenStudy (anonymous):

the teacher was solving the test problems and then got to the bonus question and then he just wrote down the limits and looked at the class like "do you get it"? and then the whole class did the ahhhh i got it kind of sounds and i didn't want to look like an idiot and didn't ask any questions.

OpenStudy (anonymous):

let me try to plot these limit and see if they mean anything

OpenStudy (anonymous):

i wish i had maple or something
