Evaluate integral_S integral (x - 2y + z) dS. S: z = 16, x^2 + y^2 le 1
vovikov84 [41]

S is the disk of radius 1 parallel to the x,y-plane and lying in the plane z=16. Parameterize this surface by

\vec r(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+16\,\vec k

with 0\le u\le1 and 0\le v\le2\pi. Take the normal vector to S to be

\vec r_u\times\vec r_v=u\,\vec k

(the orientation doesn't matter because this is a scalar surface integral)

Then

\displaystyle\iint_S(x-2y+z)\,\mathrm dS=\iint_S(u\cos v-2u\sin v+16)\|u\,\vec k\|\,\mathrm du\,\mathrm dv

=\displaystyle\int_0^{2\pi}\int_0^1(u^2(\cos v-2\sin v)+16u)\,\mathrm du\,\mathrm dv=\boxed{16\pi}

Please help me i rlly need it
iogann1982 [59]

Answer:

8.2

Step-by-step explanation:

Use cosine law:

BC² = 7² + 9² - 2(7)(9)cos(60)

BC² = 67

BC = sqrt (67)

BC = 8.1853

BC = 8.2 (nearest tenth)
