MaplePrimes - answers and comments on Question, explanation of steps

infolevel

Doug Meade — Thu, 25 Jun 2009 20:42:16 Z

The traditional way of getting some idea about what Maple is doing is to use the userinfo and infolevel commands.

userinfo is used by programmers to provide intermediate information about a command.

Users use the infolevel to control how much information they see, and which procedures information they want to see. The easiest use is to turn on the reporting from all commands:

infolevel[all] := 100;   # it's not unusual to set this to be much higher
                                     100

Then, when you try to simplify an expression you might see something like this:

simplify( sin(x)^2+cos(2*x)-3*sin(x)^4 );
simplify/do: applying  commonpow  function to expression
simplify/do: applying  power  function to expression
                                      2           4
                         -3 + 7 cos(x)  - 3 cos(x)

For more information about infolevel, please see the help page for userinfo and infolevel.

There are also a few tutors that are very handy

If you are interested in seeing steps on differentiation, integration, and limits, do the following:

Open up Maple 13
Under the Tools menu, go to Tutors, then Single-Variable Calculus

If you select either Differentiation Methods, Integration Methods, or Limit Methods, you are able to see step by step evaluations.

Take Care

How do I shut off userinfo & infolevel?

infolevel in Maple library

clso — Fri, 26 Jun 2009 19:51:20 Z

According to infolevel's help page, the following values are used as the infolevel integer values in the Maple library:

Level 1: reserved for information that the user must be told.
Level 2,3: general information, including technique or algorithm being used.
Level 4,5: more detailed information about how the problem is being solved

infolevel[all] := 1:

Just reset the appropriate infolevels to 1:

infolevel[all] := 1:

I should have included this in my original posting - sorry.
