Answer:

see explanation

Step-by-step explanation:

Given the sequence

1, 4, 9, 16, ....

has n th term

$a_{n}$ = n²

(a)

Given the sequence 2, 5, 10, 17, ......

Note the terms are 1 more than the previous given sequence, thus

$a_{n}$ = n² + 1

(b)

Given 2, 8, 18, 32, ......

Note the terms are twice the original given sequence, thus

$a_{n}$ = 2n²

Evaluate the surface integral. ??s (x2 y2 z2 ds s is the part of the cylinder x2 y2 = 4 that lies between the planes z = 0 and z

kondor19780726 [428]

The surface $S$ can be parameterized by

$\mathbf r(\theta,z)=(2\cos\theta,2\sin\theta,z)$

where $0\le\theta\le2\pi$ and $0\le z\le2$ . Then the surface integral can be computed with

$\displaystyle\iint_S(x^2+y^2+z^2)\,\mathrm dS$
$\displaystyle=\int_{\theta=0}^{\theta=2\pi}\int_{z=0}^{z=2}(4\cos^2\theta+4\sin^2\theta+z^2)\|\mathbf r_\theta\times\mathbf r_z\|\,\mathrm dz\,\mathrm d\theta=\dfrac{128\pi}3$
