Simplify expression 4(7x+5y)

Mathematics

Hello there! For this case, in order to simplify the expression, all you have to do is the distributive property. 4 is outside of the parenthesis, so we must multiply that by the terms in the parenthesis. 4 * 7x is 28x. 4 * 5y is 20y. There are no like terms in this case, so it stays put. There. The expression simplified is 28x + 20y.

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
