demioI've constrained z to 0 <= z <= 1
But I'm having a hard time figuring out the constraint to y
zaphyBeebleask _|||_ :) he knows more math than me :)
_llll_what does "figuring out the constraint to y" mean?
jkjkI read that to signals (same kinds of frequencies, same amount, but different order) have the same fourier spectrum (kinda makes sense) BUT: How does the inverse fourier transform "know" which signal to restore ?
demiofor the integral
jkjk*to two
zaphyBeebleim out of touch with stuff
demioi need to know the boundaries of the volume integral
_llll_see, now you are making more sense
"y>=0" gives you one of the y-limits, yes?
demioyea
now I need to figure out the upper bound
in terms of z
_llll_you need to draw a picture of your solid
zaphyBeebleyeah but apprently he doesnt... the constraints canbe determined from the z equation
_llll_the easiest way is to draw it
i reckon, anyway
zaphyBeebleyeah i guess
demiobut I need to know how to get the constraint from the equations only
zaphyBeeblethey dont let u take those damn plotters to school damn it
demio:P
zaphyBeeble0 <= z <= 1 - (sqrt[x^2+y^2] - 1)^2
_llll_draw a picture. with a pencil and paper
demio..
_llll_or use your brain
demioI can't rely on drawing
_llll_oh well
Deftyusing brain is wasting neurons
unless you're already good at .. drawing in your head ,p
demiogod damned fubini
:/
zaphyBeebletoo bad dont solve something you cant visualize :)
well he previously wrote:
0 <= z <= 1 - (sqrt[x^2-y^2] - 1)^2
that blew me up :)
marltu% 2+2
mbot dead?
damn
