I do not quite understand your sheet, but having Sum(f(n), n= a .. b) and setting g:= k -> f(5*k) then Sum(g(n), n= a .. b) might be what you are looking for. So write your summands as function f.

Likewise and not caring for the discontinuity:

G:=w -> Int(eval(A1+A2,omega=w),theta=0..2*Pi, method = _d01ajc, epsilon=1e-3);

Digits:=15;
plot(G, 0 .. 50);

@mthkvv 

My point is: Maple uses the conventions (or I get you wrong), I do not want to discuss conventions

@markweitzman 

Here it may be simple/elegant - but what about running up to Pi + Pi/4 or Pi + Pi/2 ?

@vv 

Maple uses the conventions in Abramowitz & Stegun or DLMF, https://dlmf.nist.gov/

I am not aware of a commitment though, say through Maple's documentation

@maple123 you already have 2 examples on treating such a task, I will not do the 3rd.

@Carl Love I see what you mean: integral = antiderivative + constant(y),
though the tasks ignored any constants and therefore are not quite wellposed

But ignoring such presentations would be a restriction for parametric integrals (and I was viewing at it as such)

The second question was also asked later by maple123 and answered by a different user. That post vanished (https://www.mapleprimes.com/questions/231854-How-Can-I-Find-My-Question-In-Maple), but here is a sketch:

Write it as Int(diff(u(x,y),x)^2,x) + Int(diff(u(x,y),x$2)*u(x,y),x) = A + B.

Then IntegrationTools:-Parts(A, (diff(u(x,y),x))^1) + B gives you the desired result

I consider that as a bug (using an old Win and Mpl 2021 Testversion).

As workaround I tried for your example of the triangle:

- export in RTF-format: works, but formulas are displayed ugly and difficult to read

- export as HTML: works fine, print from there using an external pdf-printer

I see - you mean the online documentation, sorry ... personally I almost never need or use it

I do not miss that. You seem to assume that (all) users have Latex installed. Why they should?

@vv 

Doesn't your limit mean that t is real (for Maple)?
