Misprints as of April 15, 2015:

• Page 16, line 14 from bottom: "and the two types" should be "the two types"

• Page 27, last line: "we have no information"
• Page 31, line 5: "note that"
• Page 49, third paragraph in Exercise 3.5 should read:
"Then compute three different exact solutions and the corresponding right-hand sides by means of the three examples provided in gravity. Notice that ..."
• Page 49, line 12 from bottom: after "for n = 32" add "and d = 0.25.
