thanks a lot, sorry about the lack of detail, i was trying to type it before my laptop battery died... what i meant was what ben said. i was looking for the derivation in specific.

Why does particle emission follow a poisson? Thanks in advance

i mean like u know how (n+1)! = n!(n+1) can we do something like that for (2n-1)!

Any Takes?

oh and i think that z goes from 0 to 5x not 0 to x

thx so much... i couldn't see how the x=y would effect

i tried again but the sketch doesn't make perfect sense, its almost like the boundaries don't limit it completely, so the volume appears to be infinitly large i have the z=5x plane, x=y plane, z=0 plane and the parabolic cylinder x=4y^2... i don't see the use of being given the x=y plane...

Hey guys, i need some help... I am trying to compute the triple integral z dx dy dz, where R is the region bounded by the parabolic cylinder x= 4y^2 and the planes z = 5 x, y = x, z = 0 ... i can't seem to get the limits of integration... when i sketch it it doesn't quite make sense... thanks in...

thx a lot HallsofIvy, much appreciated!

Hey I am trying to compute the volume of the region under the plane z=7 x + 4 y + 34 and over the region in the xy -plane bounded by the circle x^2+y^2=4 y. i can't seem to get it... like i i know that the circle is x^2+(x-2)^2=4 so 0<r<2 and 0<theta<2pi this is what i try double integral of...

hey my first post, try to think of it like this... A car and a truck DONT have the same stopping distance when initally going the same speed, it maybe possible to have the same stopping distance if you have big brakes on the truck. Ffriction=(mu)*(Normal), so the larger the mass (normal becomes...
