Homework Statement
Given the vectorfield
[tex]\textbf{F}(r) = y^2\bold{i} + z^2\bold{j} + x^2\bold{k}[/tex] and the surface S defined by a mapping
[tex](\rho,\phi) \in [0,1] \times [0,2\pi] \mapsto \bold{r}(\rho,\phi) = 4\bold{i} + (1+\rho cos(\phi))\bold{j} + (2+\rho sin(\phi))\bold{k} [/tex]
show that S is a disk parallel with the plane yOz with the center at [tex]\bold{r}_c = 4\bold{i} + \bold{j} + 2\bold{k}[/tex]
Homework Equations
The Attempt at a Solution
I can see that I need to rewrite S is a circle and then I take y and z component of S and write them as a circle. That I get :)
But how do I use this to show that S can be viewed as plane yOz parallel with a disk?
Which theorem do I use?
