Greek Alphabet
The physical sciences make extensive use of the Greek alphabet. Since at least parts of this alphabet may be new to some readers, and because the way the lower-case letters are drawn can vary, we list in the table A.I the upper- and lower-case characters and their names. No attempt is made to list pronunciations since it is common to mix Greek and English.

Constants and Functions in Maple
We summarize below the names of a few common constants which Maple knows.
Constant Value
