you need the intersection of the two shapes, have you got that yet?

what do i integrate over though??

which function is on top and which is below for z?
 one year ago

SABREENBest ResponseYou've already chosen the best response.0
yea i never know when a function is on top or on the bottom can we plug in values to figure this out?

TuringTestBest ResponseYou've already chosen the best response.1
sure, try x=y=0 and you can find out real quick

oh, and I see I let you do it backwards, sorry

i got it right but i guessed...whats the math behind it?
 one year ago

TuringTestBest ResponseYou've already chosen the best response.1
hooray :) at the origin x=y=0, so z=x^2+y^2=0 is on the bottom, and z=32x^2y^2=32 is on top

SABREENBest ResponseYou've already chosen the best response.0
hmm i get it plug in x=y=0 to find out which ones on top which ones on the bottom

SABREENBest ResponseYou've already chosen the best response.0
could you have a look at the second question as well
 one year ago

TuringTestBest ResponseYou've already chosen the best response.1
by plugging in x=y=0 and comparing values we are asking which one is on top at that point. Unless they cross each other that goes for the whole shape the second one looks a little harder, let me see...

i got the first equation when i apply the topbottom rule
 one year ago

TuringTestBest ResponseYou've already chosen the best response.1
right, but I think we want to do this in polar anyways
 one year ago

SABREENBest ResponseYou've already chosen the best response.0
yea we do so the bottom equation is right because we want to subtract one to gt the bottom half of the circle
