Well, it IS a lens cap. Being so, it does provide protection for your lens. There is a HOWEVER, however: if you buy a filter for that 82 mm lens, be prepared for this cap to pop off at any time. I would STRONGLY suggest adding a lens cap holder (the thing with the elastic that goes over the lens barrel and attaches to the cap with a string and circular adhesive attachment).


Help answer the question about Cap Sigma
help me to do this math problem?
1.Let the surface sigma σ be the paraboloid z=x^2 + y^2 capped by the disk x^2 + y^2 <1 in the plane z=1.Verify Cap Sigma the divergence theorem for F( x,y,z) = 2xi -yzj +z^2 k2. use Green's Theorem to find the work done by the force field F(x,y) = xyi + ( 1/2 x^2 + xy) j on particle that starts at (5,0) traverses the upper semicircle x^2 + y^2 =25 and returns to its starting point along the x-axis.
