Homework Statement
let c be the curve of intersection of the cone z= sqrt(x^2+y^2) and the plane 3z= y+4, taken once anticlockwise when viewed from above.
(i) evaluate
∫c (sinx - y)dx +(x+cosx)dy + (e^z + z)dz
(ii) let s be the surface of the cone z= sqrt(x^2+y^2) below the plane 3z= y+4 and above the xy plane.
let F = (sinx - y)i +(x+cosx)j + (e^z + z)k
evaluate
∫∫s [(curlF) . nds], where n points downwards .
Homework Equations
The Attempt at a Solution
for(i) i attempted to create parameters however it creates a messy equation to integrate. i also don't know if i used the parameters correctly.
this is not homework, its the final question of a revision paper with no solutions
