Use Stokes' Theorem to evaluate S curl F · dS. F(x, y, z) = 5y cos(z) i + ex sin(z) j + xey k, S is the hemisphere x2 + y2 + z2
Alenkinab [10]

By Stokes' theorem, the integral of the curl of \vec F across S is equal to the integral of \vec F along the boundary of S, call it C. Parameterize C by

\vec r(t)=2\cos t\,\vec\imath+2\sin t\,\vec\jmath

with 0\le t\le2\pi. So we have

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

=\displaystyle\int_0^{2\pi}(10\sin t\cos 0\,\vec\imath+e^{2\cos t}\sin0\,\vec\jmath+2\cos t\,e^{2\sin t}\,\vec k)\cdot(-2\sin t\,\vec\imath+2\cos t\,\vec\jmath)\,\mathrm dt

=\displaystyle\int_0^{2\pi}-20\sin^2t\,\mathrm dt

=\displaystyle-10\int_0^{2\pi}(1-\cos2t)\,\mathrm dt=\boxed{-20\pi}

Which of these points lie on the circumference of the circle X^2 + Y^2 = 25? Circle your answer. (-3, 4) (6.25, 6.25) (9, 16) (-
Bad White [126]

Answer:

  • A. (-2, 4)

Step-by-step explanation:

<u>Given the circle:</u>

  • x^2+y^2=25

or

  • x^2+y^2=5^2

According to the equation, any point with one of the coordinate > 5 lies outside of the circle since the radius is 5 units.

The points 2, 3 and 4 have at least one of the coordinates greater than 5.

<u>Let's verify the point 1:</u>

  • (-3)^2+4^2=9+16=25\\
  • 25=25
