My gravatar was made with the following Mathematica code:

Graphics3D[{
  GrayLevel[.3], Specularity[White, 15],
  Lighting -> {{"Directional", 
     RGBColor[.3, .3, .4], {{5, 5, 10}, {5, 5, 0}}},
    {"Point", Black, {12, 3, 15}},  
    {"Point", White, {12, 3, 4}}},
  KnotData[{"TorusKnot", {2, 5}}, "ImageData"]}, 
 ViewVector -> {{0, 0, 5}, {0, 0, 0}}, Boxed -> False, 
 Background -> None, Axes -> False, ImageSize -> 1000]

comment How to find the area between two curves
Hi Alison. You need to use Pi (not pi), and == (not =). And try specifying Reals for Solve's domain. (Although that might not be the real problem.) And I wonder, section 6.1 of what?
