Question:
Let ƒ(x, y, z) = (x2 + y2 + z2)-1/2. Show that the clockwise circulation of the field F = ∇ƒ around the circle x2 + y2 = a2 in the xy-plane is zero
a. By taking r = (a cos t)i + (a sin t)j, 0 ≤ t ≤ 2π, and integrating F · dr over the circle.
b. By applying Stokes’ Theorem.

THEOREM 6-Stokes' Theorem Let S be a piecewise smooth oriented surface having a piecewise smooth boundary curve C. Let F = Mi + Nj + Pk be a vector field whose components have continuous first partial derivatives on an open region containing S. Then the circulation of F around C in the direction counterclockwise with respect to the surface's unit normal vector n equals the integral of the curl vector field VX F over S: fF.dr = [[ S Counterclockwise circulation VXF ndo Curl integral (4)

I started tutoring in college and have been doing it for about eight years now. I enjoy it because I love to help others learn and expand their understanding of the world. I thoroughly enjoy the "ah-ha" moments that my students have. Interests I enjoy hiking, kayaking, and spending time with my family and friends. Ideal Study Location I prefer to tutor in a quiet place so that my students can focus on what they are learning.
