Use the divergence theorem to calculate the surface integral ??s f · ds; that is, calculate the flux of f across s. f(x,y,z = ex

Kamila [148]

$\mathbf f(x,y,z)=e^x\sin y\,\mathbf i+e^x\cos y\,\mathbf j+yz^2\,\mathbf k$

By the divergence theorem, the surface integral can be evaluated by computing the triple integral

$\displaystyle\iint_Sf(x,y,z)\,\mathrm dS=\iiint_V\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV$
$=\displaystyle\iiint_V\left(\dfrac{\mathrm d\mathbf f}{\mathrm dx}+\dfrac{\mathrm d\mathbf f}{\mathrm dy}+\dfrac{\mathrm d\mathbf f}{\mathrm dz}\right)\,\mathrm dV$
$=\displaystyle\int_{x=0}^{x=4}\int_{y=0}^{y=3}\int_{z=0}^{z=4}2yz\,\mathrm dz\,\mathrm dy\,\mathrm dx$
$=72$

What’s -1,099 squared to the 2 power

Basile [38]

Answer:

1,458,783,255,601

Step-by-step explanation:

(-1,099)^2

Break it apart:

(-1,099)*(-1,099)

Multiply the signs and numbers:

Two negatives make a positive so you are left with just 1,207,801.

Next, you square 1,207,801:

(1,207,801)*(1,207,801)

And you get the number 1,458,783,255,601
