Simplify the expression.<br> - (m<br> m + 3n - 13)

natulia [17]

Answer:

$= - {m}^{2} - 3n + 13$

Step-by-step explanation:

$- (m \times m + 3n - 13)$

$m \times m = {m}^{1} \times m$

${m}^{1} \times {m}^{1} = {m}^{1 + 1} = {m}^{2}$

$- ( {m}^{2} + 3n - 13)$

$= - {m}^{2} - 3n + 13$

Y = 3 sin2x, y = 0, 0 ≤ x ≤ π; about the x−axis

Dominik [7]

I assume you're revolving the region with those bounds about the x-axis, and supposed to find the volume.

Via the disk method,

$\displaystyle\pi\int_0^\pi(3\sin2x)^2\,\mathrm dx=9\pi\int_0^\pi\sin^22x\,\mathrm dx$

Recall the half-angle identity for sine:

$\sin^2t=\dfrac{1-\cos2t}2$
$\implies\displaystyle\frac{9\pi}2\int_0^\pi(1-\cos4x)\,\mathrm dx$
$=\displaystyle\frac{9\pi}2\left(x-\frac14\sin4x\right)\bigg|_{x=0}^{x=\pi}$
$=\dfrac{9\pi^2}2$
