Surface Integral

<< < (2/2)

cosec(x):
Yes, the radius is constant, you are integrating the surface of a sphere (a sphere has a fixed radius) that is bounded by a cone, ie. the sphere is cut along the circle where phi=pi/4, and we find that surface, given that it is altered by funtion f=xyz. The surface is a constant distance from the origin, therefore r=1

enwiabe:
Ohhh is this a closed potato or open potato? Because if you're counting the base of the object...

cosec(x):
No, its just a part of the sphere, above, not of the cone, so its the surface of an open "weirdo potato shape"
