3. Consider the vector field F(x, y) + 2y F dr, where C is the circle (r-2)2 +y2 = 1, oriented counterclock (a) Compute wise (Hint: use the FT of line integrals. We could not use it for the circle centered at the origin, but we can use the theorem for this circle. Why?) (b) Let 0 be the angle in polar coordinates for a point (x, y). Check that 0 is a potential function for F 3. Consider the...
Multivariable Calculus Image Provided Let C be an oriented curve in R3; f = f(x,y,z) a function and F a vector field. Which of the following is true? The Answer Key (without solution) is telling me the answer is D.... I really beg you.. could you please explain the reasons behind why your answer(s) are true and others are false? While exam is soon, I am really having hard time understanding the concept--fundamentals behind it. I will promise to sincerely...
