For positive variables:

map(simplify,f) assuming positive;

Apparently, no legal consequences would arise for software companies because of the engineer using wrong results.

Adding the option style=patchnogrid, produces a nicer surface plot with such dense grids.

Be aware of inconsistent conventions.

Changing any of the words in "Numerical Integration" to lower case produces "No Matches Found". Idem, permuting them.

But the online help (when finished) + a web search may provide more useful results than the own Standard GUI help browser search tools. E.g. a Google search

"numerical integration" site:http://www.maplesoft.com/support/help/

yields three hits, while a text search for numerical integration in the help browser produces many tens of hits (no exact phrase search seems to be available). .

In Maple 13 the latter has changed to:

convert(f, trigh);
-2*I*sinh((x+1/2*Pi)*I)

By the way, I wonder whether the option name "trigh" for hyperbolic functions sounds fine to native English speakers. I find it quite confusing. Almost "trig" like for trigonometric functions, but for the termination "h". A strange hybrid. Something like "hyperb" would sound to me much more meaningful.

In systems, fake solutions may arise with option AllSolutions:

solve({cos(x)>=1,sin(x)=0},x,AllSolutions);
                             {x = Pi _Z1}

solve({cos(x)>=1,sin(x)=0},x,AllSolutions);

These packages should be merged, or at least collaborate, instead of collide, as they deal with the same subject.

You can use the permuted order:

with(plottools):with(geometry):
a:=arc([0,0],1,Pi/2..0,color=blue,thickness=3):
triangle(T,[point(A2,0,0),point(A1,0,4),point(A3,7,0)]):
b:=draw(T,thickness=4):
plots:-display(a,b);

Or use the long name form:

with(geometry):
a:=plottools:-arc([0,0],1,Pi/2..0,color=blue,thickness=3):
triangle(T,[point(A2,0,0),point(A1,0,4),point(A3,7,0)]):
b:=draw(T,thickness=4):
plots:-display(a,b);

You may look e.g. here how to solve these initial-boundary condition problems for the heat equation.

You will need calculating a Fourier series. Maple does not include a package for these calculations. Hence, 'pdsolve' won't  solve such kind of problems. But you can install e.g. the contributed FourierTrigSeries package.

is sometimes helpful.

Anyways, I get ?evalf,int by a topic search for "Numerical Integration".

Oh, yes. All the system, not just help, is too much compartmentalized.

Tracing a simple call to 'latex'

printlevel:=50:

a call to an external library appears:
