I want to partially execute a large worksheet using to a point where I want to proceed with step-by-step execution . I am looking for a command that brings execution to a halt.

Threads:-Sleep(big number) and works but is there anything else that I could use.

In the same context: Execute worksheet removes all output. I would like to keep the output in the worksheet. Is that possible?

So far I have only noticed them for special functions.

For the case of Airy in 2D: Is possible the get for the input Ai(x) the output Ai(x) and not AiryAi(x)?

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?
