Sometimes this information is not needed. Example

(Int = int)(1/x, x = a .. 2, 'AllSolutions')

I had a look at help(interface).

I need tutoring on some calculus basics.

Maple does integrate the indefinite integral but not a definite version of it.

I assume that this is not possible without additional assumptions on y(x).

I tried to assume the properties continuous and differentiable.

Anything else that can be done/assumed to force evaluation the way I want?

Here is an example of how such integrals can come about

I try to understand why Maple throws 2 times an error but on a third attempt (with the same input) output is returned. Is that a new mechanism of suppression of error or warning messages and returning output up to a point where evaluation cannot further be performed.

With -sin instead of cos Maple returns output immediately. Does this mean that there is no information to the user available (yet) for this particular case?

I have expected elementwise and map to be effective. Why aren't they for this example?

(Evaluation at a point (see help(D)): In output (3) it is the first time that I see a composition of the D operator with the Eval function (vertical bar). Is that an undocumented feature or part of an answer that I could not figure out myself?)
