Question

Evaluate Double integral F*Ds where F=y (J)- z (k) and S is the surface given by the paraboloid y=x^2+z^2 and the disk at y=1

Answer 1

hmmm, what is F=y(J) - z(k) ?

Answer 2

never seen that before

Answer 3

Jk are the directional vectors

Answer 4

(j) and (k)

Answer 5

oh , we call them e here

Answer 6

e1,e2,e3

Answer 7

ohhh, we use (I,J,K) to represent Vectors in X,Y,Z

Answer 8

can you draw the problem using a diagram,,below
