• Know the tangential and normal components of acceration.
• Be able to state Kepler's three laws.

• Be able to use Green's theorem to compute area in terms of a line integral.
• Be able to use Green's theorem to compute line integrals: primarily around closed loops, but also possibly for non-closed curves (where you must add a curve or curves to make a loop).

• Be able to find the boundary of a surface, and figure out its induced orientation.
• Be able to compute the flux of a vector field through an oriented surface using a parameterization of the surface (including getting the orientation right!).
• Be able to compute a flux integral without using a parameterization in the special situations where the relationship between the vector field and the normal vector can be determined without a parameterization.
• Know Stoke's theorem and use it to compute work integrals around loops.
• Be able to use the divergence theorem to compute flux through a closed surface.
• Be able to apply the divergence theorem to solid regions with cavities
• Be able to complete a non-closed surface into a closed surface by adding a surface. Do this to evauate a difficult flux integral involving a complicated vector field whose divergence is simple.
• Be familiar with the vector field F(x,y,z) =r -3 r where r = xi+yj+zk and r=|r|. This field has divergence 0, but is not defined at the origin. Moreover, the flux of this vector field through a sphere centered at the origin (and any radius), oriented outward, is 4 π . We used this and the divergence theorem to study the flux of F through any closed surface.
