(9)Integrate f(x,y,z)=x-3y^2+z over the line segment X
joining the point (1,1,0) to the point (1,1,1).
(11)Find the circulation of the field F(x,y,z)=(x^2-y)i+4zj+x^2k
around the curve C in which the plane z=2 meets the cone z=(x^2+y^2)^1/2
counterclockwise as viewed from above.
这两题不知道怎麽下手@@
请各位高手帮忙一下
谢谢~
