More with 3D

We talked about equations of planes and vectors perpendicular to the planes. The homework is from two sections of Brown.  Read the corresponding explanations in the book.  They are very clear, have lots of examples and better pictures than anything I can draw.  (This reading should be considered part of the homework!)

HW p.451/25-28, 32, 38  and  p.467/1-4, 7-9, 13, 15, 16
