You can plot less lines (see linespace in the code above) or make the lines thinner (surface properties).

For that, have a look at the online documentation:

@acer Thank you.

It's a bit confusing that the complete integral of the first kind got its own symbol but not the complete integral of the second kind.

It seems that it is widely used in this way.

What do you mean by guiding?

What do you mean by "3D chart"? `Do you mean the output of plot3d?

@ecterrab 

 Selecting with the mouse and scrolling takes too long, but this way it works acceptably and(!!!) preserves the output:

S1: place the cursor where to stop

S2: Select all the above with Crtl+Shift+Home (on Windows)

S3: from the menu: Evaluate -> Selection

Thank you

Before I read your post I was quite happy with what I saw on the screen.

Now I see these "absurdly" long negations everywhere. Here a sample from a text passage

I clearly am in favour of a shorter version.

@Carl Love 

That's a good workaround!

Since 2d is not affected by tiny rendering (below: left 4k right 2k) and the rendering changes without Maples GUI and kernel dooing anything, I think that the issue is more openGL related.

Thats how the the output looks like when I change back to 4k (without execution of any commands. i.e. it is the same plot as above):

(A while ago I contacted support with that issue but they could not reproduce it because they had no 4k monitors to test.)

@Carl Love 

My example was misleading. Older Maple version did not allow to use implicitplot3d without ranges so I put something that did not match the OPs screenshot.

I can exactly reproduce the tiny fonds and how it looks differently if I change to 2k (with Maple 2023)

@acer 

Thank you. I looked at the wrong spot for the Airy question. For "_M" I can't find anything.

Is there more information available in the console window?

@ecterrab 

I can see that turning the output of options off by default is not a good idea. I was more interested to switch the display of for a particular output not to expose readers who are not familiar with Maple with that detail. 

In this case I would of course also hide Maple Input.

Did you forget to attach the code?

@acer too easy. Thanks

I tested int warnings on another elliptic expression

https://www.mapleprimes.com/questions/233304-How-To-Find-The-Inverse-Function-Of

This time it behaved as I would have expected (i.e. no supression of warnings after repeated tries). It seems that it depends on the type of integrand. I will leave it like this. Thank you

@acer 

This comes from applying the chain rule to

and then integrating over varphi.

That's a formal step to avoid using differentials. The left hand side integrated is nothing else than the time (as a function of an angle of a pendulum in this case. If varphi_t=varphi_0 the pendulum has made a half period.) It is easy to do this with differentials but Maple does not provide such a caculus (for a good reason).

Alternativley to that I could change variables (in this case I could not apply and equation that relates the variables because this is function varphi(t) that I try do derive).

So far the left hand side does not evaluate to t(varphi_t)-t(-varphi_0) and I am obligied to replaced this confusing term by t manually.
