Physics 410: Maple

• Important: When working with xmaple (the GUI version of maple).
  1. Ensure that the Num Lock key is OFF. Otherwise certain control keys such as Ctrl-j, Ctrl-k etc. will not work as advertised in the GUI. (Num lock is typically usually located in the upper left hand corner of the keypad portion of a keyboard.)
  2. Save (Ctrl-s) your worksheet frequently to guard against software/hardware crashes. (This comment clearly applies to the use of any editing/composition software.)
• Important: Please note the following difference betweens Maple V.4 (the documentation handed out in class) and Maple 8 (the version currently installed on the lnx machines).
  1. The percentage sign, %, replaces the double-quotes character, ", as the shorthand for "last result"; similarly, %% replaces "" for "next-to-last result".
  2. The double pipe symbol, ||, replaces the period/dot, ., as the concatenation operator.
• Getting your own copy of Maple: Ron Parachoniak (Hennings 203) has a Maple 9 CD that you can borrow to install maple on your own machine. Be prepared to leave something of value (driver's license, credit card, cash etc.) as collateral to ensure prompt return of the CD.

• Sample Maple source file example. Use the Maple read command to input such a source file.
• Sample Maple procedure ladd which sums the elements of a list.
• Maple source file tladd which tests ladd, and execution trace.

• Maple procedure polyinterp for computing Lagrange interpolating polynomial (PS)
