Use Stokes' Theorem to evaluate C F · dr where C is oriented counterclockwise as viewed from above. F(x, y, z) = xyi + 5zj + 7yk
REY [17]

By Stokes' theorem,

\displaystyle\int_C\vec F\cdot\mathrm d\vec r=\iint_S(\nabla\times\vec F)\cdot\mathrm d\vec S

where S is the surface with C as its boundary. The curl is

\nabla\times\vec F(x,y,z)=2\,\vec\imath-x\,\vec k

Parameterize S by

\vec\sigma(u,v)=u\cos v\,\vec\imath+u\sin v\,\vec\jmath+(8-u\cos v)\,\vec k

with 0\le u\le9 and 0\le v\le2\pi. Then take the normal vector to S to be

\vec\sigma_u\times\vec\sigma_v=u\,\vec\imath+u\,\vec k

Then the line integral is equal to the surface integral,

\displaystyle\iint_S(\nabla\times\vec F)\cdot\mathrm d\vec S=\int_0^{2\pi}\int_0^9(2\,\vec\imath-u\cos v\,\vec k)\cdot(u\,\vec\imath+u\,\vec k)\,\mathrm du\,\mathrm dv

\displaystyle=\int_0^{2\pi}\int_0^9(2u-u^2\cos v)\,\mathrm du\,\mathrm dv=\boxed{162\pi}

The sum of two angles is 180 degrees. Their difference is 70
navik [9.2K]

Step-by-step explanation:

x+y=180

x=180-y------(i)

x-y=70------(ii)

Now,

Putting the value of x in equation (ii)

x-y=70

(180-y)-y=70

180+2y=70

2y=70-180

2y= - 110

y= - 110/2

y= - 55

Again,

x=180-(-55)

x=235

x-y=70

x-(-55)=70

x+55=70

x=70-55

x=15
