For this question stokes theorem is required.

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.

Evaluate ∮(sinx-y)dx+(x+cosz)dy+(e^z+z)dz

I would very much appreciate if someone could find the right integrals..and arrive at the correct answer.

.i have spent ages on this question ...thanks.

I used the following eqn ∫∫(∇xF).ndS

then the next step would be to find the cross product.

the normal is 1/√10(j-3k) taken from 3z=y+4

The integrals I got for this are:θ btwn and 2π

phi goes from o to 1 ???

the answer in the answers is 3√2π
