Question

The following series of questions are regarding the crossword puzzle at the end of Stanley Farlow's Partial Differential Equations for Scientists and Engineers.  (Home-school mom here, who thought it would be "fun" to assign this crossword puzzle, but then realized, I did not have the answer key. Oops.)  So your help is greatly appreciated.
